Netview looks at the CDP for purposes of finding connections between
unnumbered serial interfaces when you have already discovered the two
devices involved. That's one of the reasons it pulls the routerSysname
field. CDP stores sysnames. For the purpose of discovering those next hop
nodes, it is more likely to get the information it needs from the arp cache
of the router.
As you know, Netview does not use sysnames in lieu of resolved names for
labeling. The messages you are seeing are mostly informational. If you are
trying to keep your network neat, you might take action and resolve them.

Hi list,
I'm having a problem with a set of cisco 7200 routers & netmon.
Using NV 7.1.3 with FP1 on NT4 sp6
In netmon.trace I keep getting the following;
Cisco router x.x.x.x interface XX, ignoring UNRESOLVED nextHop:
GLASTONBURY_
I'm getting these for each interface of each of the core routers which have
~600 interfaces each. GLASTONBURY_ isn't in DNS, but I thought this was
some part of the Cisco CDP & Netview would still be able to resolve where
the nextHop really was.
I've seen a few older posts on the archives, but I've not seen one that
says I don't need to worry about this, or that it's some config problem
with netview/the router...
Anyone got any views??
