How to bridge vlan and physical interface on asr?

[carensantos23]

I will connect a server on g0/0/2 of ASR with IP add 1.1.1.5 and gateway 1.1.1.1. I want that device to be part of vlan 10 on g0/0/0. What configuration should I place on g0/0/2? As much as possible, I dont want to use bridging because I cannot remove the IP address on vlan 10 (it is a production network). Is there any other possible way I can do it?

Current config:

interface GigabitEthernet0/0/0.10

 encapsulation dot1Q 10

 ip address 1.1.1.1 255.255.255.224

 ip flow ingress

 ip flow egress

 interface GigabitEthernet0/0/0.20

 encapsulation dot1Q 20

 ip address 2.2.2.1 255.255.255.224

Any suggestion will be highly appreciated.

Thanks,

Hi ,

 Solution for your requirement is ip unnumbered Command , under your g0/0/2

interface GigabitEthernet0/0/2

ip unnumbered GigabitEthernet0/0/0.10

Hi Sandy,

        Thanks. The link is up but cannot ping the directly connected device, I use my laptop and the server with the same subnet of 1.1.1.1 for this test. I am using GLC -T on SFP port and the link is 'UP'. On forum, some people say GLC -T works fine and some say it's not (not supported by asr). I ordered SFP -GE -T and will test again.

here's #sh ip int br output:

Gi0/0/0.100            1.1.1.1     
GigabitEthernet0/0/2   1.1.1.1   (g0/0/2 inherit the ip of g0/0/0.100)

I tried on gns3 and my lab router 2900 series but encounter this 'Point-to-point (non-multi-access) interfaces only' whenever I configure #ip unnumber... on physical interface.

I am willing to try any other suggestion or solution.

Hi 

 To check interface gig 0/0/2 operational status . From your Router Ping to any destination using  source as interface gigabitEtherent 0/0/2 . 

Supported T Connector for ASR is SFP-GE-T.

SFP-GE-T

Cisco 1000BASET SFP

The 1000BASE-T SFP module operates on standard Category 5 wiring of up to  328 feet (100 m) link length.

Hi Sandy,

      Thanks.

The new 1000base -T SFP did not even bring the link up, unlike the first one that I used. I inserted the  GLC -T back on g0/0/2, the link went up and do # ping 8.8.8.8 source g0/0/2.

ASR#ping 8.8.8.8 so gigabitEthernet 0/0/2
% Invalid source interface - IP not enabled or interface is down

here's #sh ip int br output:

Gi0/0/0.100            1.1.1.1     
GigabitEthernet0/0/2   1.1.1.1   (g0/0/2 inherit the ip of g0/0/0.100)

Does this mean that the inherited IP by g0/02 from g0/0/0.100 is not valid to work?

Hi , 

  Are you able to ping from the HOST connected to gig0/0/2 to the gateway IP address 1.1.1.1 .

Share me your router config .

Hi,

I can't ping directly connected device to the 1.1.1.1 eventhough the link is up.

Current config:

interface GigabitEthernet0/0/0.10

 encapsulation dot1Q 10

 ip address 1.1.1.1 255.255.255.224

 ip flow ingress

 ip flow egress

 interface GigabitEthernet0/0/0.20

 encapsulation dot1Q 20

 ip address 2.2.2.1 255.255.255.224

!
interface GigabitEthernet0/0/2
 ip unnumbered GigabitEthernet0/0/0.100
 negotiation auto
!

here's #sh ip int br output:

Gi0/0/0.100            1.1.1.1     
GigabitEthernet0/0/2   1.1.1.1 

Thanks,

Caren
