Cisco ASR 1004 - How to create L3 interface

Hello All,

I am in the process of staging a couple of two new Cisco ASR 1004's which are located at two locations with a WAN link in between.  I need to set up connectivity between servers plugged directly into each ASR router across the WAN link.  The ASR has 16 gig interfaces (gi0/0/0 - gi0/0/7 and gi0/1/0 - gi 0/1/7), and a management interface (gi0).  I have connected the WAN link to gi0/0/0 and put an ip address on it.  The servers will be plugged into the remaining gig interfaces.  I tried to create an SVI (vlan interface) in an attempt to create an L3 interface to support routing to these servers but these routers don't allow SVI's to be created.

Does anyone know how to put these server connected ports on a vlan and to create an L3 interface to provide routing to them?

Thank you,

Re: Cisco ASR 1004 - How to create L3 interface

Hello Adil,

the preferred solution would be to add L2 LAN switches on each site.

If this is not possible you should deploy /30 IP subnets one for each server/ASR 1004 GE interface and you can configure each port as a router port.

Example: associated to gi0/0/1 on router port server side associated to gi0/0/2 on router port server side


and so on


according to feature navigator IRB (integrated routing and bridging 9 is supported on ASR 9000 but not on ASR 1000 This could be a cool feature for your application.
