Thanks to the list for all the help you've given me so far! Another question: I am running BIRD 2.0.2 and peering with a host that is announcing vpn4 mpls and vpn6 mpls routes. The vpn4 mpls routes are working, but all of the vpn6 mpls routes appear as withdrawn routes. I'm not sure why -- I looked at the packet capture in Wireshark and the UPDATE messages containing the IPv6 routes all show zero for Withdrawn Routes Length. Any ideas? Here's the result of 'show protocols all peer1' (addresses changed): bird> show protocols all peer1 Name Proto Table State Since Info peer1 BGP --- up 14:35:04.353 Established BGP state: Established Neighbor address: 192.168.42.1 Neighbor AS: 65321 Neighbor ID: 192.168.42.1 Local capabilities Multiprotocol AF announced: vpn4-mpls vpn6-mpls Route refresh Graceful restart 4-octet AS numbers Enhanced refresh Neighbor capabilities Multiprotocol AF announced: vpn4-mpls vpn6-mpls Route refresh Extended next hop IPv6 nexthop: ipv4 ipv4-mc Graceful restart Restart time: 120 AF supported: vpn4-mpls vpn6-mpls AF preserved: 4-octet AS numbers Session: internal multihop AS4 Source address: 192.168.100.1 Hold timer: 12.954/15 Keepalive timer: 0.005/5 Channel vpn4-mpls State: UP Table: vpntab4 Preference: 100 Input filter: ACCEPT Output filter: REJECT Routes: 9771 imported, 0 exported Route change stats: received rejected filtered ignored accepted Import updates: 9771 0 0 0 9771 Import withdraws: 20 0 --- 20 0 Export updates: 9771 9771 0 --- 0 Export withdraws: 0 --- --- --- 0 BGP Next hop: 192.168.100.1 IGP IPv4 table: master4 Channel vpn6-mpls State: UP Table: vpntab6 Preference: 100 Input filter: ACCEPT Output filter: REJECT Routes: 0 imported, 0 exported Route change stats: received rejected filtered ignored accepted Import updates: 0 0 0 0 0 Import withdraws: 2785 0 --- 2785 0 Export updates: 0 0 0 --- 0 Export withdraws: 0 --- --- --- 0 BGP Next hop: :: IGP IPv6 table: master6 -- Chris Herdt https://osric.com/chris/
