Hi Guys,
We have a cisco7206 router which is going to be replaced with an ASR1002 router. The 7206 has some interfaces in a BVI-group - the config of which i am trying to translate over into IOS XE (which runs on the ASR1002).
Basically i have the following config:
!
bridge irb
!
bridge 120 protocol ieee
!
bridge 120 route ip
!
interface GigabitEthernet0/2
no ip address
duplex auto
speed auto
media-type rj45
no negotiation auto
!
interface GigabitEthernet0/2.120
encapsulation dot1Q 120
no ip redirects
no ip unreachables
no ip proxy-arp
bridge-group 120
!
interface GigabitEthernet0/2.3999
encapsulation dot1Q 3999
ip address 10.10.10.10 255.255.255.248
no ip redirects
no ip unreachables
no ip proxy-arp
ip authentication mode eigrp 77 md5
ip authentication key-chain eigrp 77 XXXX
delay 1005
!
interface BVI120
ip address 172.10.10.10 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
!
which i am trying to find the equivalent config of, on IOS XE. The nearest answer i could find is posted here:
https://supportforums.cisco.com/thread/2162439
however this seems to work fine for physical interfaces but not for logical subinterfaces which is what i have.
FYI the 7206 is running c7200-advsecurityk9-mz.124-9.T7.bin, and the ASR1002 is running asr1000rp1-adventerprisek9.03.04.02.S.151-3.S2.bin.
Any information anyone can provide on how to translate this config from IOS to IOS XE would be much appreciated. Thanks in advance

Hello Danne,
the BDI concept is not limited to physical interfaces, but it uses the concept of Ethernet Virtual Connect as specified in Metro Ethernet forum
see the links below
and
the difference should be
interface Gig0/1 service instance 1 ethernet encapsulation dot1q 120 bridge-domain 1 interface Gig0/2 service instance 1 ethernet encapsulation dot1q 120 bridge-domain 1 interface BDI1 ip address x.x.x.x
to be noted you can assign an encapsulation dot1q also to the BDI interface as explained in the first link.
Hope to help

Thanks for the reply Giuseppe.
So are you saying that Gi0/2 that is configured like this on the 7206 router:
interface GigabitEthernet0/2
no ip address
duplex auto
speed auto
media-type rj45
no negotiation auto
!
interface GigabitEthernet0/2.120
encapsulation dot1Q 120
no ip redirects
no ip unreachables
no ip proxy-arp
bridge-group 120
!
interface GigabitEthernet0/2.3999
encapsulation dot1Q 3999
ip address 10.10.10.10 255.255.255.248
no ip redirects
no ip unreachables
no ip proxy-arp
ip authentication mode eigrp 77 md5
ip authentication key-chain eigrp 77 XXXX
delay 1005
!
interface BVI120
ip address 172.10.10.10 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
!
...can now be configured like this on the ASR?
interface GigabitEthernet0/2
no ip address
speed 1000
no negotiation auto
service instance 1 ethernet
encapsulation dot1q 120
bridge-domain 120
!
!
interface GigabitEthernet0/2.3999
encapsulation dot1Q 3999
ip address 10.10.10.10 255.255.255.248
no ip redirects
no ip unreachables
no ip proxy-arp
ip authentication mode eigrp 77 md5
ip authentication key-chain eigrp 77 XXXX
delay 1005
!
interface BDI120
ip address 172.10.10.10 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
!
and i would configure Gi0/3 (which is the second interface in the bridge-domain) on the ASR similarly?
I tried creating a service instance under a subinterface but it doesnt seem to work, so this is the only way i can think of doing it that might.

Hi Danne,
Did your configuration work for you on the ASR?

We're you able to get this working with the sub-interface?
