NX-OS show ip bgp rib-failure equivalent

I utilize the: show ip bgp rib-failure command in IOS to check for BGP learned routes which did not get installed in the routing table.
However, in my Cisco 7009 with Enterprise licensing, I cannot find the equivalent command to check for RIB failures and the reason for the RIB failure.

I've ran into the same issue on IOS-XR code and hasn't been able to find any equivalent in XR docs.
Just wondering if you have found some more information on your NX code?

BGP RIB

I am learning advance bgp ....having query :
BGP uses different types of routing table..i.e 1) adj-rib-in (unprocessed routes which are received from neighbors)
2) adj-rib-out (routes which are sent by router to its neighbors)
3) local bgp table: (remained routes after process on adj-rib-in & rib-out) Best routes from local bgp table is forwarded to ip bgp talbe...
Q1. is it right??
Q2. how can i see these three table separately... is there any command to see only adj-rib-in or rib-out etc ??
Q3. Is there any concern of command
       show ip bgp neighbors [address] advertised-routes
       show ip bgp neighbors [address] received-routes
       show ip bgp rib-failure
S@ndy...

Hi S@ndy,
Ad Q1: Almost correct. I believe that looking into RFC 4271 is worth a try, and the RFC puts it very nicely:
Adj-RIB-In
The Adj-RIBs-In contains unprocessed routing information that has
been advertised to the local BGP speaker by its peers.
Adj-RIB-Out
The Adj-RIBs-Out contains the routes for advertisement to specific
peers by means of the local speaker's UPDATE messages.
Loc-RIB
The Loc-RIB contains the routes that have been selected by the
local BGP speaker's Decision Process.
In particular, the Loc-RIB are not "the remaining" routes but simply routes that have been selected from Adj-RIB-In and locally injected routes as the best paths. These routes would be attempted to be installed into the router's routing table and would also be candidates for advertisement to other BGP peers.
Ad Q2: To see what routes have been received from a particular neighbor (Adj-RIB-In), use show ip bgp neighbor X.X.X.X routes. To see what routes have been sent to a particular neighbor (Adj-RIB-Out), use show ip bgp neighbor X.X.X.X advertised-routes. I am not sure if there is a command to display the Loc-RIB; I do not know of any.
Ad Q3: The advertised-routes shows the Adj-RIB-Out for the neighbor. The received-routes is relevant to a deprecated feature called Soft Reconfiguration that is beyond the topic of this discussion. The rib-failure shows you a set of routes from Loc-RIB that could not be installed into the router's routing table, if there are any. Most often, this is caused by the same network being already present in the routing table with a better administrative distance.
Best regards,
Peter

Show ip bgp not showing all BGP Paths

Hi,
We've setup BGP as shown in the diagram.
Now Router Router A and B are peers of each other. Router A peers with ISP A and Router B peers with Router B.
The issue we have is that Router B knows how to get to router C via eBGP connection to ISP B router or via ISP A, which is advertised via iBGP from Router A.
But ....
Router A only shows in "show ip bgp" about network Router C via ISP A.
If I do a soft clear of bgp information on Router A I then see both paths to Router C via ISP A or ISPB, but once BGP is converged im only seeing best path via ISP A. Can anyone explain why the path via ISP B is not shown on Router A? we are using local preference in a route map to say prefer router A over Router B to exit the network to get to router C.
Synchronisation is disabled. Router A and B are running the same code of IOS and also have similiar configs.
My assumption is that becuase of the local preference Router A stops listing path via Router B in the BGP table. This thought doesnt make complete sense to me ???? In my test lab I always see all paths to exit the AS.
router#show ip bgp 192.168.100.0

Thanks
B

I've just lab'd this and it is the local preference.
If I remove my route map I see all paths as expected. Once I apply my route-map which matches ips and assigns the local preference then I see the shown behaviour.

How can I see "show ip bgp neighbors" for only VPNv4 enabled?

Hi,
I have only VPNv4-BGP-neighbors defined (IPv4-cfg is inactivated).
Is there any command showing the status of the VPNv4-neighbors ??
I am missing a command like "show ip bgp sum", "show ip bgp neigh" for VPNv4.
I use Cisco7206 with 12.2(14)S at the moment
What about neighbor status (established, number of prefixes, statistics updates/keepalives,....)
Regards,
Chris

Hi,
I found the command I searched for:
sh ip bgp vpnv4 all sum
sh ip bgp vpnv4 all neighbor
Thanks,

Under show serverfarms what does failures mean?

When u do show serverfarm u see connections failures. How do u dig into what serverfarm connection failures are?
When u do show serverfarm detail it does not tell u much
Eg:
serverfarm : 5.7.133.98-80, type: HOST
total rservers : 1
----------connections-----------
real weight state current total failures
---+---------------------+------+------------+----------+----------+---------
rserver: nj09mhe0004
172.28.8.33:2098 8 OPERATIONAL 0 14112 224
So we have 224 connection failures what do they mean?

Failures are counted when the server does not respond to a SYN from ACE or responds with a RESET.

"Show Description" for podcasts--key equivalent?

Is there any way, directly or via a decent fudge, to have a command-key equivalent for the "Show Description" selection you can get for a podcast via the contextual menu? I use this a lot, and right-clicking over and over is irritatingly slow. Yes, I know you can leave the window open, but I also use this on my MacBook, where screen real estate is somewhat precious.
I tried Show Description from Doug's Applescripts
http://dougscripts.com/itunes/scripts/ss.php?sp=showdescription
but not only does it bring up a different window (not the same one you get from the contextual menu) but what you get is mostly code and not easily read. I don't want to edit the code, just see the long description.

After selcting the value from F4 press enter, it will go through the PAI and PBO. Write the code to select the description from that check table and pass into that description field. In the attributes of that description field, goto Program tab Check the check box Output field and Output only.
Check the sample program:
TABLES: addr1_data.
DATA: ws_country_desc TYPE t005t-landx,
      okcode TYPE sy-ucomm.
CALL SCREEN 100.
*&      Module status_0100 OUTPUT
      text
MODULE status_0100 OUTPUT.
IF NOT addr1_data-country IS INITIAL.
    SELECT SINGLE landx FROM t005t INTO ws_country_desc WHERE
                                  land1 = addr1_data-country
                              AND spras = 'EN'.
ENDIF.

RAID5 Utility Shows Prefailure but no failure light on drive.

I have an Xserver (Late 2009) that has the 3 internal bays setup with 2TB drives each in a RAID5 array. (Plus an external 16TB RAID Array as well.) The RAID Utility shows that Bay 2 his a drive in a prefailure state. However, the light on the drive itself is green, not orange or red, as I might expect. The server is still up and operational. I have a replacement 2TB drive in hand to swap it out. However, I'm concerned that my drive light is green instead of orange/yellow or red to guide me to the failing hardware so I can replace it and begin the automatic rebuild process.
Any insight on what I'm seeing here?
Thanks!
Here's what the server drive bays look like:
And this is what my RAID Utility shows:

How hard was it to replace the backplane? I have a DL385 G2 with the same issue, except on two drives (slots 0 and 1).

Show mls qos interface statistics equivalent command on Cat6500 SUP720-3B?

Hi all
Is there a command on the SUP720-3B that is similar to the show mls qos interface gi0/x statistics command on the access-layer series switches (3560 etc.)?
I'd like to see the incoming and outgoing DSCP/COS values in number of packets.
Thx :)

Hi,
You can use this command:
SUP720#show queueing interface xx
You should be able to see all that information there.
Hope this helps.

IPS4240 in bypassmode-auto cause BGP peering failure

Recently installed IPS4240's running inline. With "bypass-mode auto" the BGP peering (with password) between 2 routers either side of the IPS unit drops. The error logs indicate bad MD5 hash on both units. In "bypass-mode on" BGP peering with password is fine.
Anyone know a fix or the cause?

This is probably being dropped or modified by some of the "normalizer" engine signatures in the IPS. Basically the IPS in inline mode does a lot of TCP checks and drops or modifies packets with certain bits set. It probably doesn't like the fact the MD5 hash is set as TCP option bit 19 and is modifying it somehow, which then fails your authentication on the remote peer.
Go into whatever configuration tool you're using and enable the "produce-verbose-alert" on all the 13xx signatures (1300-1330). Then check your alerts for an alert with a victim/attacker IP addresses of your BGP routers, see what signature it was that actually fired, then disable that signature (or add a filter so that it doesn't fire for that IP address pair anymore). This will stop it doing whatever it is doing to your BGP packets and it should work from then on.
It'll probably be one of the sub-sigs under 1330, as this does a lot of different checks on various parts of the TCP packet.

Advanced auditing turned on for both success and failure and overide setting enabled, but no failure audits showing.

Just wondering if anyone else has had this issue and found a solution. the policy has been applied
and enforced through the default domain policy. New category success events are showing up, but
no failure audits.

Maybe there is no failure event?

Load balance not happening in BGP

Dear Friends,
As per I know local BGP process may implement equal-cost load-balancing to the paths that:
Have the same set of path attributes up to the MED (weight, Local Preference, Origin, MED)
Are of the same type (both learned via iBGP or eBGP)
Have the same IGP cost to reach their NEXT_HOP IP address
If the above conditions are met andmaximum-paths [ibgp]is configured under the BGP process, BGP will install multiple equal-cost routes into the local RIB and use them for load-balancing. We call the above condition as load-balancing conditions for BGP.
As all the above criteria are matched still BGP is not doing load balance. Please find below routing table:

The BGP cost community modifies the BGP path selection process.
the "pre-bestpath" point of insertion was introduced in the BGP Cost Community feature. This POI is applied automatically to EIGRP routes that are redistributed into BGP and carries the EIGRP route type and metric. This POI influences the best path calculation process by influencing BGP to consider this POI before any other comparison step effectivefly forcing BGP to use IGP-like selection rules.

BGP route-reflector next-hop issue

Hello,
I have a small GNS3 lab that is working with one exception: I cannot ping loopback0 on RRc2 and RRc3 from RRc1.
RRc1, RRc2 and RRc3 can all ping loopback0 on SmileyISP and RRc2 and RRc3 can ping each others loopback0
interfaces.
I am broken between the two route-reflectors: RRS1 and RRS2.
Given these conditions:
1) Do not configure any IGP.
2) No static routes
How do I get connectivity from RRc1's loopback0 interface to RRc2 loopback0 and RRc3 loopback0?
I used a route-map to set the next hop, but I am obviously doing something wrong.
I am providing relevant show command outputs, router configs, and the GNS3 topology.net config.
You will have to change the image and working directories to match your computer.
Not quite sure where I am going wrong.
Any help would be greatly appreciated.
Thanks.

BD,
Ahh...
OK. In the original article, the author states that the final piece with the route map
NEXTHOP was supposed to fix the reachability issue. Obviously it doesn't.
After reading your last post, I looked more carefully at the output from 'sh ip bgp'
on each of the client routers and I realized that several of the next hop addresses were
wrong for some of the prefixes.
1) I completely removed the 'neighbor RouteReflectors route-map NEXTHOP out'
from both RR's. Then I ran 'sh ip bgp' on the clients and noted a change in the next hop addresses. Still wrong, but it changed.
2) I then tried next-hop-self from the RR's to the clients, but it did not change from where
it was after I completed step 1. I am not sure why there was no change. (actually, see the very end of this post)
3) I then applied my version of the route map: route-map NEXTHOP permit 10
                                                                             set ip next-hop peer-address
to the RR's with this: neighbor RRClients route-map NEXTHOP out
That fixed it. All three clients have as their next hop for all prefixes their respective
RR's (which is what they should have for this topology).
I have full connectivity everywhere, even loopback to loopback between all clients.
1) THANK YOU for pointing me in the right direction.
2) If I may ask, why did next hop self fail? More specifically, I saw no change at all
in the next hop for the advertised prefixes. Is it because next-hop-self should be used
for eBGP peers and all of the RR's and clients are all within the same AS?

NX-OS show ip bgp rib-failure equivalent
