Hi. We're upgrading our remote site routers from 2600/3600s to 3845s. In Network Topology I'm selecting LAN i/f ip address(as opposed to the WAN i/f ip address) for management, after the installation of the new router. But as soon as I select, the router disappears from the map & Topology Services.
I've deleted it from CS/RME and seed devices; rerun devicediscover and data collection and then reintroduced it into seed device and repeated the discover and collection but still it doesn't appear in topology services. It is, however in RME/CS and devicediscovery and data collection. Although only as an ip address in data collection. It doesn't show in DCR under CM but does under CS & RME.
Anyone got any suggestions, please?
