Configuring HSRP and VRF in EVC model L2VPN XR

Hi,

 

I have created an L2 Switching configuration using L2VPN, Is there a way for me to add VRF and HSRP to this setup? here is my current L2VPN config

 

======================

nterface Bundle-Ether2
description 
mtu 9216
!
interface Bundle-Ether2.999 l2transport
encapsulation dot1q 100
rewrite ingress tag pop 1 symmetric
 
interface TenGigE0/0/2/2
description 
bundle id 2 mode active
cdp
interface BVI100
ipv4 address 10.10.100.10 255.255.255.0
!
l2vpn
bridge group 999
bridge-domain BD999
interface Bundle-Ether2.999
!
routed interface BVI100
!============================
! Thanks

yes you can, here is an example of the config

 

vrf TEST
address-family ipv4 unicast
 import route-target
  1:1
 !
 export route-target
  1:1
 !
interface GigabitEthernet0/0/1/2
cdp
!
interface GigabitEthernet0/0/1/2.1 l2transport
encapsulation dot1q 1
rewrite ingress tag pop 1 symmetric
!

interface BVI1
vrf TEST
ipv4 address 1.1.1.3 255.255.255.0
!
l2vpn
bridge group TEST
 bridge-domain TEST
   interface GigabitEthernet0/0/1/2.1
  !
  routed interface BVI1
 !

router hsrp
interface BVI1
 address-family ipv4
  hsrp 1
   preempt
   address 1.1.1.1

Thanks, its working, however, for HSRP.  if I shutdown one BVI interface,  the standby router also gets deleted. I was assuming the standby router will take over but it doesnt look like it does

When both BVI's are up

If you shutdown the BVI interface of the HSRP-Active device then you are not going to see the standby transition into the Active state from that same device where you have just shut the interface, because you have disabled the interface over which it "sees" that peer.    Are you saying that after shutting down the BVI100 then when you look on the config of the "other" router it has not taken over ownership of the HSRP virtual-address ??
