A little bit of strange behavior, first off my
setup:
Cisco 2501 with IOS 12.0.9 Enterprise
Cisco 2504 with IOS 11.2 Enterprise
Cross over DTE<->DCE cable connecting their
Sync Serial ports together
Right now im running hdlc b/w them, i've tried ppp,
frame with maps, no inv-arp, etc.. it made no difference.
then network on the interfaces is
192.168.1.0/30
I have connectivity, ping works great, trace does
NOT work hardly at all though.
RouterA-DCE#Trace RouterB
then it hangs for a good 3-4 seconds
normally the trip times are 8ms * 4ms
as you can see, the middle time is a *, debug ip
icmp shows the port unreachables being sent and recv'd (two of
them).
Now the oddball part is, if you feed it no ip
classless, the router broadcasts (255.255.255.255) the icmp packets out all the
interfaces except Serial0, unicast on it.. this makes it take even longer!
(normally 3 broadcasts 1 unicast/unicast reply, 3 broadcasts, etc)
Any idea what's up? NO other networks
configured on the router (which also gets rid of the broadcasts), routing table
just has the connected route to 192.168.1.0/30 out Serial0
