WS-SUP720-3B full BGP table

Hi all,
I have a Catalyst 6500 with SUP720-3B whith 1GB memory (MEM-Sup720-SP-1GB= and MEM-MSFC3-1GB=) which is going to receive full BGP table, I know about the limitation of 256K routes of SUP720-3B, but with the following memory will it be able to hande the full BGP table?
Thnx in advance,

I don't believe so. For full Internet routes, you'll want a XL variant.

ASR1002 crawls when installing BGP Full Internet table

hi all,
I have an ASR1002/ESP10 and I have 2 or 3 peers that are sending me FIRT. When I filter with route-maps the incoming announcements, I'm keeping about 3K routes and everything is fine. But when i try to remove the incoming filters, then the ASR1002 tries to install the FIRT into the FIB and this results in the ASR1002 crawling and becoming unresponsive (while it is installing the FIRT into the FIB).
Is that normal? Is there a way, to tell the ASR to install the FIB with a slower rate, in order to have CPU power for the rest of the tasks. Do you also know if this influences forwarding performance of the router?
thanx,
Sp.

Tracking your 2911's CPU usage will provide an indication of how hard it's being "worked".
I've attached a later Cisco document that better documents expected and recommended performance levels for various ISRs. (NB: in that document, you'll see a 2911 is only recommended for up to 35 Mbps.)
PS:
BTW, running full BGP with your two ISPs, hoping to obtain optimal performance, really doesn't. What actually works much better, if you're licensed for it, is Cisco's PfR technology (which will work fine with just a default to both ISPs).

Difference between sh ip bgp & sh ip route? BGP tables and main routing table.

Difference between sh ip bgp & sh ip route?
sh ip bgp :::: loc-rib ?
sh ip bgp nei x.x.x.x advertised-routes : adj-rib-in.
sh ip bgp nei x.x.x.x recieved-routes : adj-rib-out.
sh ip bgp nei x.x.x.x routes : loc-rib ?
sh ip route = rib ? if yes does it mean its loc-rib ?
so in a given router with bgp running, will there be 5 tables (sh ip bgp; adj-rib-in; loc-rib;adj-rib-out; sh ip route) ? if yes where are they saved ?

sh ip bgp
shows the BGP table (where are stored info coming from BGP update)
sh ip bgp nei x.x.x.x advertised-routes
shows networks that your router will advertise to a specific neighbor
sh ip bgp nei x.x.x.x recieved-routes
shows advertisement received from a specific neighbor; networks (NLRI) filtered with route-map distribute-list,... are included (Inbound soft reconfiguration must be enabled)
sh ip bgp nei x.x.x.x routes
shows only routes sent by a specific neighbor and not filtered or discarded (i.s accepted)
sh ip route
show routing table; it contains the best route for each network (best is first of all the lowest administrative distance, then the lowest metric)

How to use full qualified table names in RPD

Hi,
We are implementing the BI Financial Analytics, we have a requirement to use diffrent user accounts for DAC , ETL and OBIEE
DAC, ETL we are using user as XXOBI
For OBIEE RPD we have to use user with read only access such as XXOBI_APP
How can i make the changed to BI server / RPD to use full qualified names.
I have tried to select the Full Qualified table name property in Oracle Datawarehouse connection pool setting.
If i enable that all my sql query is showing tables as catalog.dbo.w_party_d ( my tables in physical layer showing under catalaog -> dbo -> all tables and joins)
Any help in this is appreciated.
Thanks

KrisAre you saying you just need to access the database using different accounts? If that is the case, why dont you just update the connection pool settings like username and password with XXOBI_APP account which you are supposed to be using for OBIEE?

CRS, IOS-XR: local IGP route not installed in BGP table when learned from RR

Hello,
We use CRS routers in our IGP/BGP network core, some of which are acting as BGP originators and reflectors (RRs) for IPv4 unicast. We also use CRS routers as Internet PEs. The problem we have is between those PEs and the core routers.
Premise: each Internet PE is terminating customer cisrcuits and injects those downstream routes in IGP (via redistributing static, or just learned via IGP from a downstream router). The core (P) routers then learn those routes from the PE via the IGP. Two of the P-routers act as BGP originators and install the necessary routes in BGP using the network statement. These routes are mostly supernets (i.e. summarized), but some coincide with IGP routes, as learned from the PEs. The P-routers acting as RRs then reflect all iBGP routes to all IPv4 unicast BGP speakers in the network, including the Internet PEs (we also have BGP peers on those PEs, which is why this is necessary).
Problem: if a specific downstream route, learned on an Internet PE via IGP (i.e. from downstream), is then received by that PE from an RR via iBGP (i.e. from upstream), the route is not installed in the BGP table (the output of the show bgp x.x.x.x/xx command is: Network not in table)
Question: does anyone know why this is happening? This is concictent on all of our CRS PEs. As far as I am aware there is no BGP rule that would explain this behavior. We don't expect the PE to prefer the iBGP route over the IGP route, but that should not prevent it from learning it and installing it in the BGP table... The only discrepancy I could think of is that the IGP route has a next-hop pointing downstream, whereas the the same route, learned over iBGP has a next-hop pointing upstream. Then again,this shouldn't prevent the route to appear in the BGP table....
Your help would be appreciated!
Thanks!

Hi !
If I am understandung you correctly then Split Horizon is the keyword
Because if the route is learned from downstream BGP drops any same path information learned from upstream
SPLIT-HORIZON only applies to distance-vector routing protocols. In case of BGP, it simply means that a prefix learned via a peer is not advertised back to that peer.
Split horizon will simply block out routes with the same neighbor as the next-hop for the router

BGP Table Version - erratum

There appears to be a error this tech-note:
BGP Table Version
http://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/116511-technote-tableversion-00.html
Document ID: 116511
The Peer Table Version is used in order to track which peers must be informed of which prefixes for which there were changes in the best path. The Peer Table Version of each peer is checked against the Prefix Table Version of the prefixes. If the Prefix Table Version of a prefix is lower than the Peer Table Version, then BGP must send an update for that prefix to that BGP peer. For example, if the peer 10.1.1.2 has a Peer Table Version of 60, then that peer is up to date for all prefixes with Prefix Table Version of 60 and lower. The router must send a BGP update for all prefixes with a Prefix Table Version that is higher than 60.

Hi Ivan,
The bgp table version number is a Cisco software (ios/iox) specific implementation. It's not part of the RFC. Therefore it cannot be retrieved via snmp.
Best regards,
Shane

Full routing table exchange in Link State Routing?

In link state routing protocols, full update that happen every 30 minutes, does the routers exchange the whole routing table with each other? Or exchange something else, not full routing table. If not the whole routing table, what they are exchanged?

The interval depends on the routing table. OSPF will send out a fresh copy of the LSA (link-state advertisement) every 30 minutes. ISIS will send it every 20 minutes. Only LSAs are sent, not the routing table.

Hi Hin
The Red Highlighted Metrics are the IGP Metrics to reach the MP-iBGP Peer which is the 8th Criterion for Best Path Selection Algo..
If we will check for a show ip route 10.254.4.254/253 we will see the IGP metric as to be as the one highlighted in red above.
Hope this helps to answer your query..

Details :
We are experiencing erratic database performance. It was upgraded from 9i to 10g along with PS software upgrade. A job that runs on one day in 12 hrs(that is high in itself) would take more than 24 hrs another day.
We have Test and Staging envs on other servers which do not have performance issues of production magnitude. The test, staging dbs are clones of prod, created by ftp'ing files from one location to another, not sure if that makes any difference but just pointing out.
On Prod db some symptoms which baffle me are :
1) sql executing for over 40 minutes, check the plan and it is using an "incorrect" index, idx1. Hint sql with "correct" index, idx2, and it runs in few seconds. result set <400 rows. Cost with hint with idx2 is HIGHER. This scenario is still understandable as CBO is likely to pick a lower cost.
- But why is there so much discrepancy in cost and response time?
- what is influencing the CBO to pick an index which is obviously not the fastest response time?
2) sql plan shows FTS , execution time , runs forever . But a hint with index in this case shows the cost is LOWER and response time is in seconds, so why is CBO not even evaluating this index path? Because as I understand the CBO, it will always pick the lower cost plan.
What is influencing the CBO. Is it system stats? or any other database parameter? or the hardware ? the large SGA?? histogram ?? Stats gathering?? is there is any known issue with DBMS_STATS.AUTO_SAMPLE_SIZE and cardinaility?
Where should I put my focus?
What am I looking for ?
I do have Jonathan Lewis's Cost-Based Oracle Fundamentals which I have just started so perhaps I will be enlightened but while I read it, it would be of immense help to get some advice from forum gurus.
At this time I am not posting any exec plan or code, but I can do so if required.
Thanks,

Proc fails with sqlcheck=full accessing tables across a link to non 11g db

I am trying to compile programs that were upgraded from 9i to 11g and having issues whenever I try to compile code that accesses non 11g databases across a link when sqlcheck is anything other then syntax.
If I have a select such as
select distinct a.ID_NUM, b.value1, b.value2, ...
from table_a a, table_b@external_db b
where a.ID_NUM = b.ID_NUM and a.process_name='REPORTS';
This compiler sits and hangs for a few minutes then aborts. This problem occurs in Pro*C, Pro*Cobol as well as Oracle Forms.
The query works fine under sql*plus. The compiler just can't handle it.
A work around under Pro*C is to use sqlcheck=syntax when compiling any code that accesses across a link. However this isn't a good workaround since it won't catch errors such as a typo in a column. This also won't work in forms, but a work around is to convert the selects into a view. However that isn't a good workaround due to the number of queries that would need changing.
Has anyone else seen this issue and found out what needs changed in the Database for this to work. I tried searching Oracle's web site but couldn't find any solution.

I'm not sure why I never thought of searching MetaLink, but thanks for the pointer! It doesn't match my circumstances, however. The Bug smells like a view not being queried in the APEX development tool itself -- i.e. the IDE's coding needs changing, not necessarily those apps created with the IDE.

Please advice me? How can I do this?

Hello Umit,
If I properly understand you want to test your connection towards ISP and BGP route exchange. I would assume your ISP uses different BGP AS compare to yours. In this current setup I see ASR9k and 7200 have the same BGP AS meaning this is iBGP. In this case we have to have full mesh between iBGP peers as routes are not sent back to other iBGP peers.
I don’t know which exactly 7200 emulates ISP, but we need to configure eBGP between ASR9k and that 7200 (different BGP AS).
Note, you use “update-source MgmtEth0/RSP0/CPU0/0”. That is not recommended as there is no routing between management and other forwarding interfaces. Configure a loopback and use as an update-source.

Ampliacion memoria 7600 de 1GB que usa BGP

Buenos días¡¡¡¡
Tenemos este equipo, un router 7600 que se utiliza para bgp e intercambia 500.000 rutas con un proveedor internacional Cogent.

Hello.
As I understood the problem: FIB is limitted to 192K prefixes (while full BGP view requires 500K+).
This is due to the RP you are using - RSP720-3C-GE, this is not because of RAM memory.
Do be able to process full BGP table you need XL version, for example, RSP720-3CXL-GE.
PS: please find datasheet here - http://www.cisco.com/c/en/us/products/collateral/routers/7600-series-routers/product_data_sheet0900aecd8057f3b6.html
PS2: please write your questions/comments in English.

Recommendation for the Core router

Hi all,
we are hosting provider and we are looking to buy additional router. Right now we have Cisco 6500 with SUP720-3BXL supervisor as a core router which sometimes has a problems because of very weak CPU.
Because of that we are searching for the real router, not switch.
Basically our needs are:
- at least 4 x 10Gbps ports
- at least 80Mpps throughput
- capable to deal with 2 Full BGP tables and at least 30 BGP peers
Any recommendation from your side would be appreciated. It could be also Juniper or Brocade.
Thank you very much in advance!
Ismir

IPv6 on internet gateway

hi,
we have 12410 GSR (PRP2) as internet gateway peering with 6 global ISP , and receive full internet routintg from them, CPU is high especaily at BGP scanner process,we are planning to enable IPv6 on this internet router so we can not expect what will happened with the performance and CPU,please advise.

Ahmed,
I do not understand what are you asking here. But if you are asking what platform I would be recommanding for a defaultless router running both a full BGP table in v4 and v6 well, I am not qualify to recommand such platform but I would recommand to start with an impementation plan. Decide wht you want to achieve and a timeline.
Also if you are running a production network, be very wary of changes.
I would rather deploy a second platfome and start using it for v6 leaving alone the v4 production network. Otherwise, you might end up disrupting service.

7600 or ASR 1000 Series as ISP EDGE WAN

Hi experts,
I want your opinion on something.
We currently have 6 STM1 and will soon have an additional 2x STM4.
The existing STM's are connected on a 7600.
We are planning to do a major upgrade in order to cater for the additional STM4 and will be grateful if i can have your views on the matter.
Right now we cannot accept full BGP table from our upstream provider due to the low mem on the 7600.
So we are thinking on either going towards two 7600 with SUP3cXL which will be able to cater for the full BGP table + we need to buy additional line cards. Or we go towards the ASR1000 series, which i think might be an overkill, but am definitely thinking of future growth.
Thanks to advise.
Regards,
Steve

Thanks vmiller.
We don't need any additional cards apart for the POS ports and 3X10G interfaces.
Plus we need something that will be able to cater for the whole BGP table.
I was task to build a business case on the matter. But it will be a bit difficult to convince the business on the go about of the ASR (if you know what i mean). So my business case needs to be solid.
Anyway thanks for your help.
Regards,
Steve
