Disabling an ASBR from Filtering VPNv4 Routes by VPN Targets

Disabling an ASBR from Filtering VPNv4 Routes by VPN Targets


By default, the PE filters received VPNv4 routes based on VPN targets. The routes passing the filter are added to the routing table, and the others are discarded. If the PE is not configured with a VPN instance, or the VPN instance is not configured with a VPN target, the PE discards all the received VPNv4 routes.

In Inter-AS VPN Option B, you do not need to configure VPN instances on the ASBRs. An ASBR must save all the VPNv4 routes and advertises the VPNv4 routes to the remote ASBR. In this case, the ASBR must accept all the VPNv4 routing information without the VPN target filtering.
