Inter-As Multicast VPNs

So let me get this right. If you share an IGP domain and your loopbacks for each individual PE are advertised into the IGP then you do not require the PIM RPF Vector feature?

ahhh I think i get this, its becuase of the next hop value right?

  • Multicast VPN Extranet Support doesn't work after reload

    Hi!
    We have Cat6500 with configured Multicast VPN Extranet Support feature. After reload of the 6500 customers in the receive MVPN cannot get mcast stream. We connect test device into source MVPN on that 6500 - everything is OK, mcast stream is available.
    Workaround is "no mls ip multicast/mls ip multicast". After these commands mcast in the receive MVPN works fine.
    IOS 12.2 SXJ2
    Looks like a bug. We have several Cat6500 but only two of them have this issue.
    Does anybody faced with such trouble?

  • Multicast VPN support in RV042?

    Hello,
    A quick check of the user manual for the RV042 didn't reveal in crystal clarity whether the RV042 will tunnel multicast packets (between two RV042s).
    What I'd like to create is a VPN between two different offices. Some of the applications use multicast, and it's crucial that these apps 'see' each other in both offices (via VPN).
    The RV042 manual does mention a "multicast pass through" setting, but it didn't mention whether enabling this applies to a VPN connection established between the two offices, such that any multicast packet on LAN #1 is reflected to LAN #2 (and vice versa) through the VPN.
    Has anyone used RV042s to create a VPN between to locations/offices, and turned on multicast pass through? Have you found that apps which use multicast (e.g., iChat on Mac OS X, Bonjour advertised infranet websites, etc.) have their multicast traffic properly appear on both LANs?
    Thanks,
    Keith

    Are there any Cisco [or Linksys by Cisco] routers which support Multicast VPN (multicast packets tunneled over VPN)? Looks like there are a number of white papers on this topic, but I've yet to identify a particular model with this functionality.
    Thanks,

  • Multicast VPN QoS

    Hi,
    How do we configure QoS for MVPN on 7600. IOS is 12.2(33)SRC. There is no support for the command set ip dsp tunnel <value>. Is there any other way.
    Regards,
    Prakash

    Hello Prakash,
    Cisco MVPN implementation uses multipoint GRE tunnels to forward multicast packets from customer network via provider network.
    So for MVPN QoS applies what applies to unicast traffic.
    the multicast packet is carried inside a GRE header with source and destination that are PE loopbacks on the provider network.
    I'm not sure but the GRE header TOS byte should be a copy of the carried packet's TOS byte.
    If so just have in the core links' schedulers classes that classify traffic based on ip dscp or MPLS EXP (match-any)
    see
    http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/guide/mvpn.html
    and for PFC QoS
    PFC QoS processes both unicast and multicast traffic.
    http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/guide/qos.html#wp1481021
    Hope to help

  • Multicast -- Multicast VPN --- XRv

    Would like your assistance please regarding below quesitos
    1- As you know to verify multicast we can use ping.
    My problem is that when you ping using source loopback address it does not work [spare-mode is configured normally under loopback] however when you configure using outgoing interface it pings normally
    What could be the reason for this ?
    2- Does XRv simulator works fine with multicast. I am having very strange behavior is that OIL list is always null although source is directly connected. Not sure if its a bug or XRv issue

    Hi Sherif Ismail,
    I encountered this and checked around. It seems that XRv supports Control-Plane features fully - BGP/IGP/LDP/PIM/etc. will work. However, Data-plane is supported with limitations.

  • RP Address in MULTICAST

    I have few doubts about Multicast RP address
    We have MPLS ISP backbone network, here two P routers are configured as RP address(IN GLOBAL) and MSDP is running between them.
    Now, my doubts are
    All the Multicast customer we are giving is under MVPN only, if dense mode no RP concept, if sparse mode MVPN have a separate RP. Then what the use of Global RP and MSDP??
    I come across MSDP for inter domain multicasting, do we need to run MSDP with other ISPs?? if so, is it advisable??
    Pls clear my above doubts!!
    Thanks in advance!!

    Hi Sankar,
    All the Multicast customer we are giving is under MVPN only, if dense mode no RP concept, if sparse mode MVPN have a separate RP. Then what the use of Global RP and MSDP??
    CE multicast (or simply c-multicast) and SP multicast (or simply p-multicast) are totally independent. As you mentioned, even if Customer multicast is sparse mode, the RP should be from VRF. RP from SP global cannot help with VRF multicast (Else you need complex leaking). Global RP is required if the P-multicast is sparse mode, inorder to establish the MDT tunnel. MSDP is required if you provide some inter domain multicast.
    I come across MSDP for inter domain multicasting, do we need to run MSDP with other ISPs?? if so, is it advisable??
    MSDP can be iether used for Inter domain or with Anycast RP. Basically MSDP is the protocol used to update any active source details to otehr RP in same domain (in case of Anycast) or different domain.
    You may have to check if you have inter-as design or anycast to understand the need for MSDP.

  • Multicast vrf

    Good Day! I have got a task to play multicast traffic through mpls (at least between the same vrf). I have 3 switches 3750 ME, sw1, sw2 and sw3. Multicast source host is connected to sw3 int fa1/0/6, receiver host is connected to sw1 int fa 1/0/5, respectively. Both interfaces are in vlan 100 (just the same vlan number). Interface vlan is in vrf green. Switches are connected back to back sw1-sw2-sw3 via gigabit interfaces (dedicated for mpls) like ce1/pe1-p-pe2/ce2. In addition, sw1 and sw3 are rr-clients for sw2. To check multicast traffic I use multicasttest utility (http://www.mikkle.dk/multicasttest/). Multicast group address for test is 224.237.248.237. Multicast traffic walk from host 192.168.1.3 to 192.168.2.2. Also, there are vl 100 interfaces on switches in vrf green created just for check proper connectivity.

    Hi Evgeny
    Unfortunately the multicast VPN feature is not supported on the 3750 ME platform even though the commands are present . This is also mentioned in Cisco Feature Navigator. There are no plans to implement this on this platform.

  • Multicasting on Cat4507 - wrong feature set ???

    Hello gurus,
    I've been trying to enable inter-vlan multicast on Cat 4507 switch. Now I've read, that all you need is
    "ip multicast-routing" and "ip pim parse-mode" for interfaces on switch. First command works fine, the second - doesn't : here is a reply from switch
    switch(config)#int Gi1/1
    switch(config-if)#ip pim ?
    % Unrecognized command
    switch(config-if)#ip ?
    Interface IP configuration subcommands:
    access-group Specify access control for packets
    arp Configure ARP features
    dhcp DHCP
    igmp IGMP interface commands
    verify verify
    Is it just a problem with feature set or am I missing something ?
    Thanks,
    Alex

    Hello Alex,
    you need a layer 3 to configure multicast on, e.g. a VLAN interface:
    interface Vlan2
    ip pim sparse-dense-mode

  • Maximum LSP on Inter-AS vpnv4/ipv4

    Hi Luc
    Thank you for your reply, in fact we are in the process of using Option B (ASBR-to-ASBR). We have all the configs in place just did not activate the neighbors pending confirmation. We are using Eng5; I would expect CAM/TFIB to be able to hold these prefixes, I seem to have noticed that the weakest processor can handle up to one million. Yet, it is not written anywhere on these specifics.
    Thanks

    Hi Fernando,
    In MPLS VPN networks, 17000 vpnv4 prefixes is not that much. You can have hundreds of thousand of vpnv4 prefixes.
    You did not specifiy which option A,B, C or D you are running. For option A and D, the scalability could become an issue because you'll have many logical links between the ASBRs, one for every VPN shared between the 2 autonomous systems. This is a known limitation factor in these two designs and it is a pain to operate such a model, starting from a certain scale. Each new VPN shared between the 2 autonomous systems will lead to the creation of a new logical link on the ASBRs.
    Option B and C do not have this and are hence more scalable and easier to maintain operationally. What inter-as MPLS VPN brings is the concentration of the LSPs on the ASBRs, instead of having them spread over many PE and P routers in a non-inter-as MPLS VPN network. But, 17000 prefixes should be ok on a 12k router.
    Thanks,
    Luc

  • Mpls forwarding for multicast

    hi,
    dose anybody can tell me that if current IOS support label switching multicast traffic in the core mpls network? i search the cco and find some information only about support multicast traffic in mpls/vpn.
    could you answer this question or give me some links to read, thanks a lot :-)

    On the Cisco Feature Navigator you can look for:
    Multicast-VPN: Multicast Support for MPLS VPN
    http://tools.cisco.com/ITDIT/CFN/Dispatch
    As fare I remember there is a special range Labels reserved for Multicasting but can't find this any more in the RFC
    I think its an inportand feature for service providers if they want to connect customers that use Multicasting
    Hope this help

  • BGP and MP-BGP

    What is difference between BGP and MP-BGP? and what is the exact application of both?

    Multiprotocol Extensions for BGP (MBGP), sometimes referred to as Multiprotocol BGP or Multicast BGP and defined in IETF RFC 4760, is an extension to Border Gateway Protocol that allows different types of addresses (known as address families) to be distributed in parallel. Whereas standard BGP supports only IPv4 unicast addresses, Multiprotocol BGP supports IPv4 and IPv6 addresses and it supports unicast and multicast variants of each. Multiprotocol BGP allows information about the topology of IP Multicast-capable routers to be exchanged separately from the topology of normal IPv4 unicast routers. Thus, it allows a multicast routing topology different from the unicast routing topology. Although MBGP enables the exchange of inter-domain multicast routing information, other protocols such as the Protocol Independent Multicast family are needed to build trees and forward multicast traffic.
    Multiprotocol BGP is also widely deployed in case of MPLS L3 VPN, to exchange VPN labels learned for the routes from the customer sites over the MPLS network, in order to distinguish between different customer sites when the traffic from the other customer sites comes to the PE router for routing.

  • OSM-2+4GE-WAN vs new 7600-ES20-GE3CXL card

    Please can you provide me information about differencess between those 2 modules, considering MPLS support. I am interested in VPLS feature support. Is this new ES20 card support non H-VPLS, like situation where we have access or trunk (dot1q) port on same 7600 router on WS-X6724 SFP card where is MPLS uplink realized with this ES20 card. Generaly,which card OSM or ES20 is better solution for MPLS (L3VPN, EoMPLS and VPLS)feature.

    The 7600-ES20-GE3CXL card has following MPLS features
    Layer 2 VPNs
    ? EoMPLS with MAC learning
    ? H-VPLS (MPLS Edge or IEEE 802.1ad Edge)
    ? Flexible QinQ
    ? Layer 3 VPNs
    ? MPLS VPN (RFC 2547-bis)
    ? Inter-AS and Carrier-Supporting-Carrier
    ? Multicast VPN
