VPLS Autodiscovery Redundant CE

[mkhalil10]

Hi all

I have the below topology:

CE1 -- CSR1 -- CSR2 -- CE2

    |  ----     \  CSR3  /

I have configured full mesh iBGP between the CSR routers under the l2vpn vpls address-family

Below is the respective VPN configuration:

CSRs:

l2vpn vfi context MSSK
 vpn id 100
 autodiscovery bgp signaling ldp

bridge-domain 100
 member GigabitEthernet3 service-instance 100
 member vfi MSSK

interface GigabitEthernet3

service instance 100 ethernet

encapsulation dot1q 100

CEs:

interface FastEthernet1/1

switchport trunk encapsulation dot1q

switchport mode trunk

interface vlan 100

ip address 10.10.100.1 255.255.255.0 (CE2 is configured with 10.10.100.2)

Now , the issue is that when I shutdown CSR3 G3 interface (Connected to CE1) , I lose connectivity between the CEs even though the L2VPN is established among all PEs , as well , when I check the show bgp l2vpn vpls all I cannot figure out which one is preferred

Thanks

Hi all

As referred by Nick Hilliard , VPLS autodiscovery does not support redundancy
