Hello Dears, Please advise about the below case scenario:   I'm having Inter-AS option B EBGP peering between ASBR router in my network & an external ASBR router in another AS, after establishing the EBGP connectivity successfully, not all of the BGP VPNv4 router are being advertised to the remote ASBR Peer.   Problem was identified that there are no sufficient labels to be allocated for the BGP prefixes due to default mpls label range is lower than the number of BGP prefixes, so i had to extend the MPLS label range on the IOS-XR router to accommodate the current number of prefixes. After extending the label range to its max, not all of the prefixes are being advertised also to the peer & i need support to interpret the below output:   RP/0/RP0/CPU0:router#show mpls label table summary Application Count ---------------------------- ------- LSD(A) 4 LDP(A) 1376 L2VPN(A) 3 LDP(S) 1376 TE-Control(A) 4 BGP-VPNv4(A):bgp-default 244883 BGP-VPNv4(S):bgp-default 617509 ---------------------------- ------- TOTAL 618578   what do exactly  BGP-VPNv4(A) & BGP-VPNv4(S) refers to ???   Thanks, ...

I'm having a problem bringing BFD session up with the below scenario :   having a cisco 7600 router as a CE router, dual homed to two ASR9K routers acting as PE routers ( MC-LAG-Decoupled Mode ) static routing is the IGP in use between C7600 & both ASR9K router, VRRP is configured between the PE routers, C7600 is pointing to next-hop VRRP IP , bfd session should be running with the destination IP address of the VRRP IP. The problem is both ASR9K routers negotiating BFD session using the source IP address of the BVI interface in use, i can't source the BFD session with the VRRP IP address which is impacting the BFD session & it is always in the down state.   Any advice for a solution for that topology ?     ...
