HP NNM and Cisco routers

I wonder if anyone can help me with the following issue.

A customer of ours has got a WAN which connects the corporate office to several hundreds branch sites.

The WAN links on the main office are HDSL point-to-multipoint.

The configuration of the routers has been made from other consultants and is as follows.

The corporate's router has got a serial connected to ISP's HDSL - Frame Relay .

The Serial has been configured with several sub interfaces.

Each interface has been configured with IP unnumbered loopback x

for each sub-interfaces a loopback interface has been created with the following configuration

loopback x

ip address 192.168.0.x 255.255.255.255 ( /32 )

a static route has been added for remote networks ( ie )

ip route 172.16.0.0 255.255.0.0 s1.1

The problem we have with HP NNM is that the links to remote networks are not correctly discovered .

The loopback interfaces are discovered but connections to remote routers are not created .

We 've made a search on the HP forum but found nothing helpful

thanks

Stefano

Hi,

You need to have routes pointing to the actual IP address of the loopback interface on the next hop router and vice versa, also make sure you have layer 2 discovery on.

ip route 172.16.0.0 255.255.0.0 192.168.0.*
