Type B Inter-AS :How to limit number of route-target ?
We came across one problem in our network that we get couple of prefix from our peering partner's customer with very long ( almost more than 100) RT on our ASBR. This caused huge problem with our legacy PE router and MP-BGP session with RR went down on all our PE.
What should be solution I should look on ASBR for Type-B NNI ? Is that something we can do to limit number of RT while doing peering with our peer ?
Re: Type B Inter-AS :How to limit number of route-target ?
the bgp rr-group can be used on a Route Reflector server to decide what vpnv4 prefixes to reflect to clients referring to an ip extcommunity extended access-list using regular expression in address.family VPNv4 context
It is not a check on the number or RTs attached to the VPNv4 advertisement.
However, there is not , as far as I know, the equivalent of bgp max-as command that can decide the max acceptable AS path attribute length.
