Ah. I think I might be on to something. I see that when I do a BGP VPLS (fec 128, rfc 4761) style config, then I do NOT see the pw's active between the non-designated-forwarding multi-homed pe's... and, this seems to be automatic. (no mhoming config needed in my lab) It seems in that link there is some typos with explaining BGP VPLS and LDP VPLS. Seems that it explains on BGP Signals PW's under the section of the document pertaining to LDP VPLS, so it confuses the reader. It seems that someone should correct that document.
I did not have to configure any multihoming commands in order to cause this to occur. In the link it mentions that there are some multi-homing commands for fec 128 bgp vpls... but I didn't use that command and I still get loop prevention behavior. ( I see pw's not up and also, the non-df pe-ce link is brought down) ...with that in mind, any idea why would I need that command for fec 128 bgp vpls ? https://www.juniper.net/documentation/en_US/junos/topics/topic-map/vpls-bgp- multihoming.html "For FEC 128-routing-instances instance-name protocols vpls site site-name multi-homing" [edit] r2@lab-mx104:r2# run show vpls connections instance vpls-4761 brief | find Instance: Instance: vpls-4761 Edge protection: Not-Primary Local site: site10 (10) connection-site Type St Time last up # Up trans 10 rmt RN 11 rmt Up Oct 9 11:12:41 2017 1 [edit] r2@lab-mx104:r2# show routing-instances vpls-4761 | display set set logical-systems r2 routing-instances vpls-4761 instance-type vpls set logical-systems r2 routing-instances vpls-4761 interface lt-0/1/0.1052 set logical-systems r2 routing-instances vpls-4761 route-distinguisher 1.1.255.2:1001 set logical-systems r2 routing-instances vpls-4761 vrf-target target:64512:1001 set logical-systems r2 routing-instances vpls-4761 protocols vpls site-range 100 set logical-systems r2 routing-instances vpls-4761 protocols vpls site site10 site-identifier 10 [edit] r2@lab-mx104:r2# run show interfaces terse lt-0/1/0.1052 Interface Admin Link Proto Local Remote lt-0/1/0.1052 up up vpls [edit] r3@lab-mx104:r3# run show interfaces terse lt-0/1/0.1054 Interface Admin Link Proto Local Remote lt-0/1/0.1054 up down vpls [edit] r3@lab-mx104:r3# show routing-instances vpls-4761 | display set set logical-systems r3 routing-instances vpls-4761 instance-type vpls set logical-systems r3 routing-instances vpls-4761 interface lt-0/1/0.1054 set logical-systems r3 routing-instances vpls-4761 route-distinguisher 1.1.255.3:1001 set logical-systems r3 routing-instances vpls-4761 vrf-target target:64512:1001 set logical-systems r3 routing-instances vpls-4761 protocols vpls site-range 100 set logical-systems r3 routing-instances vpls-4761 protocols vpls site site10 site-identifier 10 [edit] r3@lab-mx104:r3# run show vpls connections instance vpls-4761 brief | find Instance: Instance: vpls-4761 Edge protection: Not-Primary Local site: site10 (10) connection-site Type St Time last up # Up trans 10 rmt LN 11 rmt LN - Aaron _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
