Per VRF Cluster-id

Hi

I am currently setting up a new VRF on a Cisco 7609 which is advertising (as a RR-Client) an iBGP route to a Juniper MX960.  This route is then getting sent back to the default route table on the 7609 but rejected due to the cluster-id loop prevention.  Although not ideal I need this route to be visible in both tables.

Is there a way of changing the bgp cluster-id per VRF rather than just globally?

Thanks

Per VRF Cluster-id

Hello Paul,

the cluster-id is configured at BGP protocol level in IOS

see

http://www.cisco.com/en/US/docs/ios-xml/ios/iproute_bgp/command/bgp-a1.html#GUID-70C0EA38-723A-4041-A4DD-A2E331D3EB55

cluster-id is configured at BGP group level in JUNOS

see

http://www.juniper.net/techpubs/en_US/junos11.4/topics/reference/configuration-statement/cluster-edit-protocols-bgp.html

I'm afraid you cannot achieve what you want in this way, because you cannot have the same iBGP peer in two different BGP groups in JUNOS (if I correctly remember).

If your objective is to pass a route locally on the C7609 between a VRF and global routing table you should think of using route leakage

Hope to help

Per VRF Cluster-id

Hi

Thanks for your feedback.

I have ended up having to use eBGP between the Cisco box and our LNS to avoid the cluster ID of the Cisco being attached to the route advertisement toward the MX960.  Although route leakage would be the best solution normally I need the traffic to go via a set path (DPI Traffic Management).
