Cisco ISR4431 bridge 1 protocol ieee doesn't seem to work on isr4400-universalk9.16.09.04.SPA.bin

[b.krautner]

Hello,

Tried do a simple bridge of ports on an ISR4431 and got the following results:

dummyroutername(config)#bridge irb
dummyroutername(config)#!
dummyroutername(config)#bridge 1 protocol ieee
^
% Invalid input detected at '^' marker.

dummyroutername(config)#bridge 1 route ip

Spanning Tree protocol for Bridge Group 1 has not been configured.

dummyroutername(config)#!

Have done this a myriad of times in the past but seems there were all on isr4300-universalk9.03.13.03.S.154-3.S3-ext.SPA.bin whilst the current one is running isr4400-universalk9.16.09.04.SPA.bin. 

Has there been some sort of change in the IOS I've not noticed?

Kind regards,

Bob Krautner

Hello

ASR's support Bridge Domain Interfaces  instead (BDI's) - here

Hi Paul,
 
Thanks for your reply. Following is the full config I was applying with confidential bits removed:
 
bridge irb
!
bridge 1 protocol ieee
bridge 1 route ip
!
bridge-domain 1
!
!
interface GigabitEthernet0/0/1
no  ip address
no ip helper-address
no vrrp 1
service instance 1 ethernet
encapsulation untagged
bridge-domain 1
no shut
!
!
interface GigabitEthernet0/0/2
no  ip address
no ip helper-address
no vrrp 1
service instance 1 ethernet
encapsulation untagged
bridge-domain 1
no shut
!
!
interface BDI1
!
#if($Dual_CPE_Redundancy_Role == "Primary")
vrrp 1 priority 105
ip address x.x.x.x x.x.x.x
#end
!
#if($Dual_CPE_Redundancy_Role == "Secondary")
vrrp 1 priority 100
ip address x.x.x.x x.x.x.x
#end
vrrp 1 preempt
vrrp 1 track 1 decrement 10
vrrp 1 ip x.x.x.x
no shut
!
#if ($DHCP_Helper1)
ip helper-address ${DHCP_Helper1}
#end
#if ($DHCP_Helper2)
ip helper-address ${DHCP_Helper2}
#end
!
router bgp xxxxx
neighbor iBGP-CE-CE update-source BDI 1
end
!

Based on that, and what you had pointed out, am I misunderstanding what relates to BVI as opposed to BDI? I.E. the following relates only to BVI?
bridge 1 protocol ieee
bridge 1 route ip
 
Thus I just don't need to use those two lines?

Kind regards

Hello @b.krautner ,

.

the old IRB commands are not needed anymore and not supported with BDI and bridge domains

>>bridge 1 protocol ieee
>>bridge 1 route ip

Your understanding is correct you don't need them . you may need a command to declare the BDI 1 as the l3 interface of bridge domain 1

Hope to help

Giuseppe
