Answer 2/28/13 8:21 PM Mark as an Answer Submit Reply with Quote Quick Reply I'm attempting to configure my CIMC access through the PCIe slot/0 backplane connection. The interface I'm pointing the unnumbered statement back to on the 3925 host device is a sub-interface in a VRF. According to the user guides, I've configured "shared lom console" and then attempted to add a route back to the CIMC through the "ucse slot/0" interface. Unfortunately, it seems you cannot specify the ucse slot/0 interface in a route statement when using a VRF. 3925(config)#ip route vrf L3 10.94.0.8 255.255.255.255 ucse2/0 % For VPN or topology routes, must specify a next hop IP address if not a point-to-point interface And you can't point the route to the sub-interface IP address... RIAB-3925(config)#ip route vrf L3 10.94.0.8 255.255.255.255 10.94.0.1 %Invalid next hop address (it's this router) I configured using the external "M" management port and have the traffic loop outside of the UCS-E, through the rest of my L2 topology, and back to the sub-interface on the 3925, but this is less than ideal since it burns a port on the L2 switch the M port is connected to (customer wants to purchase the smallest L2 switch required, so this is a problem). Is this a limitation of the code at this time or is there another method to configure this? Thanks, Patrick IOS Config snippit below: interface ucse2/0 ip vrf forwarding L3 ip unnumbered GigabitEthernet0/2.751 imc ip address 10.94.0.8 255.255.255.192 default-gateway 10.94.0.1 imc access-port shared-lom console ! interface ucse2/1 description Internal switch interface connected to Service Module switchport mode trunk ip vrf forwarding L3 no ip address ! interface GigabitEthernet0/2.751 encapsulation dot1Q 751 ip vrf forwarding L3 ip address 10.94.0.1 255.255.255.192 end

Mark as an Answer Submit Reply with Quote Quick Reply Hi Patrick, I also see the same issue with SM-SRE product so not sure if this configuration is supported in this manner. As a work around would below work? Remove 'ip unnumbered' config from ucse 2/0 and assign a static ip instead. G0/0.751 and UCSE 2/0 would still be in vrf L3. If you need to reach CIMC from outside of this router then add vrf route pointing to GigabitEthernet0/0.751 as the gateway. c3925e-2003#show run int ucse 2/0 Building configuration...

Mark as an Answer Submit Reply with Quote Quick Reply Hi Tuong, Unfortunately this does not work for us. In this customer scenario, the CICM address must be in the same network as the Gig interface, so we cannot change it to a non-10.94.0.0 address. And we can’t assign another address to the UCSE2/0 interface in the same network. I was able to make this work by bridging the UCSE2/0 interface together with the gig 0/2.751 interface and configuring the 10.94.0.1 IP on the BVI interface. I am now able to access the CIMC and was able to install ESX. This may be somewhat of a hack but it seems to work.
