Hi,
I am trying to block STP from propagating via xconnect to another site.
Base config, L2VPN is working, endpoints in Vlan200 ping each other:
interface TenGigE0/2/1/0.200 l2transport
encapsulation dot1q 200
mtu 2014
!
l2vpn
pw-class PW
encapsulation mpls
control-word
!
!
xconnect group A903
p2p lan-2
interface TenGigE0/2/1/0.200
neighbor ipv4 10.1.0.68 pw-id 22222
pw-class PW
!
But for VLAN 200, STP root priority propagates from site A (where A9K10 is) to other site B (where A903 is). It is unwanted at site B to have root for Vlan200 in remote site A.
This command does not work:
RP/0/RSP0/CPU0:A9K10(config)#interface TenGigE0/2/1/0.200 l2transport
RP/0/RSP0/CPU0:A9K10(config-subif)#l2protocol cpsv drop
RP/0/RSP0/CPU0:A9K10(config-subif)#exit
RP/0/RSP0/CPU0:A9K10(config)#commit

end
RP/0/RSP0/CPU0:A9K10(config)#
The code is 6.6.2.
On ASR903, L2 protocols do not propagate until I configure it (l2 protocol tunnel xxx)
Thank you.
