Please let me know where I'm not understand this correctly.
I have what I understand to be a LDP VPLS configured network, additionally with a functional multi-homing configuration. It's all working. shutting down the operational/designated forwarder pe-ce interface causes a good failover to the other multi-homed pe-ce side. The juniper.net link below seems to state that a PW will not be fired-off to prevent looping. I don't see this to be true. I see a full mesh of active (UP) pw's. The only thing that I observe as the loop preventing mechanism is the non-designated-forwarding interface from PE-CE is brought down. Also, in the link below it mentions the following. "For interoperation scenarios in which a PE router must support both types of NLRI (FEC 128 and FEC 129), this example also includes the signaling statement." .I'm pretty sure it's speaking of the command "set logical-systems r2 protocols bgp group my-ibgp neighbor 1.1.255.4 family l2vpn signaling" For what I'm seeing in my lab, I don't see this to be accurate either. I see that I do not get multi-homing advertisements *received* if I don't have that "signaling" command. I do see that the local site MH info is there prior to the signaling command, in the (vpls name).l2vpn.0 (only one local entry) but nothing rcv'd in the bgp.l2vpn.0 table. I'll be glad to send any output/configs if you want to see them..this is all done within several lsys's https://www.juniper.net/documentation/en_US/junos/topics/topic-map/vpls-bgp- multihoming.html my verification commands. run show route table vpls-4762.l2vpn.0 | grep MH run show route table bgp.l2vpn.0 | grep MH run show vpls connections extensive | find Multi-home run show vpls connections br run show interfaces terse lt-1/1/0.1104 r2@lab-mx104:r2# deactivate protocols bgp group my-ibgp neighbor 1.1.255.4 family l2vpn signaling r2@lab-mx104:r2# commit r2@lab-mx104:r2# run show route table bgp.l2vpn.0 | grep MH r2@lab-mx104:r2# run show route table vpls-4762.l2vpn.0 | grep MH 1.1.255.2:1000:1:0/96 MH r2@lab-mx104:r2# activate protocols bgp group my-ibgp neighbor 1.1.255.4 family l2vpn signaling r2@lab-mx104:r2# commit r2@lab-mx104:r2# run show route table bgp.l2vpn.0 | grep MH 1.1.255.3:1000:1:0/96 MH 1.1.255.6:1000:2:0/96 MH 1.1.255.8:1000:2:0/96 MH r2@lab-mx104:r2# run show route table vpls-4762.l2vpn.0 | grep MH 1.1.255.2:1000:1:0/96 MH 1.1.255.3:1000:1:0/96 MH 1.1.255.6:1000:2:0/96 MH 1.1.255.8:1000:2:0/96 MH [edit] r2@lab-mx104:r2# show protocols bgp | display set set logical-systems r2 protocols bgp group my-ibgp type internal set logical-systems r2 protocols bgp group my-ibgp local-address 1.1.255.2 set logical-systems r2 protocols bgp group my-ibgp neighbor 1.1.255.4 family inet-vpn unicast set logical-systems r2 protocols bgp group my-ibgp neighbor 1.1.255.4 family l2vpn auto-discovery-only set logical-systems r2 protocols bgp group my-ibgp neighbor 1.1.255.4 family l2vpn signaling set logical-systems r2 protocols bgp group my-ibgp neighbor 1.1.255.7 family inet-vpn unicast set logical-systems r2 protocols bgp group my-ibgp neighbor 1.1.255.7 family l2vpn auto-discovery-only set logical-systems r2 protocols bgp group my-ibgp neighbor 1.1.255.7 family l2vpn signaling [edit] r2@lab-mx104:r2# show routing-instances vpls-4762 |display set set logical-systems r2 routing-instances vpls-4762 instance-type vpls set logical-systems r2 routing-instances vpls-4762 interface lt-0/1/0.1002 set logical-systems r2 routing-instances vpls-4762 route-distinguisher 1.1.255.2:1000 set logical-systems r2 routing-instances vpls-4762 l2vpn-id l2vpn-id:64512:1000 set logical-systems r2 routing-instances vpls-4762 vrf-target target:64512:1000 set logical-systems r2 routing-instances vpls-4762 protocols vpls no-tunnel-services set logical-systems r2 routing-instances vpls-4762 protocols vpls multi-homing site site1 identifier 1 set logical-systems r2 routing-instances vpls-4762 protocols vpls multi-homing site site1 interface lt-0/1/0.1002 -Aaron Gould _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
