How to assign an IP address to a cisco asr901 interface?

[Baptiste]

Hello,

I have a Cisco ASR901 router and I want to put an ip address on an interface but the router tells me that it does not support the command.
Here is what I did:
***
C1_B(config)#int gi0/0
C1_B(config-if)#ip add
C1_B(config-if)#ip address 192.168.1.2 255.255.255.0
IP address config under this interface is not supported on ASR901
***

I said to myself that it doesn't matter, if it doesn't work I'll create a vlan and then assign it to the interface I want but it doesn't work either.
Here is the vlan configuration and the command I did :

***
interface Vlan10
description ****int gi0/0****
ip address 192.168.1.2 255.255.255.0
ip ospf 1 area 0

C1_B(config)#int gi0/0
C1_B(config-if)#sw
C1_B(config-if)#switchport ac
C1_B(config-if)#switchport access v
C1_B(config-if)#switchport access vlan 10
This command is not supported.
***
Do you have a solution to put an IP address on an interface of a cisco ASR901?
Best Regards

Hello @Baptiste ,

Cisco ASR 901 router does not support switch port configuration.

Try this:

C1_B(config)#interface vlan 10
C1_B(config-if)#description ****int gi0/0****
C1_B(config-if)#ip address 192.168.1.2 255.255.255.0
C1_B(config-if)#no shutdown

C1_B(config)#interface gi0/0
C1_B(config-if)#description ****int gi0/0****
C1_B(config-if)#no shutdown
C1_B(config-if)#encapsulation dot1Q 10

first you must config the SVI of vlan the add VLAN under the Gige  x/x interface

Thank you for your explanation.
I did it like this:
First I configured a vlan.

interface Vlan20
description ***int gi0/0***
ip address 192.168.25.1 255.255.255.0

and then I configured the interface this way

interface GigabitEthernet0/0
no ip address
negotiation auto
service instance 20 ethernet
encapsulation untagged
bridge-domain 20
