ASR1001 BDI interface

khld.saad
Level 1
Level 1

i have configured BDI interface on ASR Router (ex BDI 100) And given it Test IP 10.1.1.1/24 and it is UP and server with IP 10.1.1.2/24 can Ping BDI interface
but when we shutdown one of Sw interface ( Ex: SW-01 Port Fa0/1 ) , Ping fails .
It seems that only interface Fa0/1 on SW-01 is working and traffic going through it , but when it shutdown the interface Fa0/2 on SW-02 doesn’t carry traffic
we need to know why this happens and how we make redundancy in this case .

- The configuration on ASR Router as below :-

interface GigabitEthernet0/0/1
no ip address
negotiation auto
cdp enable
service instance 100 ethernet
encapsulation untagged
bridge-domain 100

interface GigabitEthernet0/0/2
no ip address
negotiation auto
cdp enable
service instance 100 ethernet
encapsulation untagged
bridge-domain 100

interface BDI100
ip address 10.1.1.1 255.255.255.0
no snmp trap link-status
snmp ifindex persist

Hello,

 

make sure you have spanning tree enabled globally (spanning-tree mode rapid-pvst)...

 

Also add the 'l2protocol peer stp' command to your interfaces:

 

interface GigabitEthernet0/0/1
no ip address
negotiation auto
cdp enable
service instance 100 ethernet
encapsulation untagged
l2protocol peer stp
bridge-domain 100
!
interface GigabitEthernet0/0/2
no ip address
negotiation auto
cdp enable
service instance 100 ethernet
encapsulation untagged
l2protocol peer stp
bridge-domain 100
!
interface BDI100
ip address 10.1.1.1 255.255.255.0
no snmp trap link-status
snmp ifindex persist

the command not available with me as below
(config-if)#l2protocol peer ?
<cr>

Hello,

 

can you post the full configuration is your ASR ?
