Re: [nv-l] Problem with discovery routers

Well, I'm not sure what is happening,
but have you looked anywhere for clues?
NetView seldom, if ever, deletes and
object without a trap, so what's in trapd.log when this occurs? And
what's in the netmon.trace file?
Is it possible that this fourth router
is not being discovered by it's loopback address but by some HSRP or other
duplicate address instead?
For best results you should define a
loopback address on the router and put that address in the netmon seed
file so there is no mistaking what the main interface is. And the
loopback cannot be one of your duplicates, It should also be in DNS,
and resolve correctly both forward and backward.
By default, white is the color for unreachable
objects, so for some reason I'd say that at some point after discovery
,the NetView box doesn't think that it has connectivity to that box. That
indicates to me that there is some weirdness in it's interface table but
that's just a guess.

Hi,
We have 7.1.4 over AIX 5.1
I have a problem. We have 4 central routers
(CISCO), with more than
200 interfaces frame-relay each one. In order to have high availability,
the IPs are duplicated among them. Each router it has a fixed unique
IP.
I have activates the option of duplicated IPs in netmon.
Netview represents to me, correctly, to three of
them. The other
puts it of white color, we do ping to him and it is put green, but if
nmdemandpoll is done to him, netmon delete the object. What can be
happening?
