Subject: Vofr help on Cisco2610 and Cisco3620
Hello all:
Need someone to provide wisdom and assitance on my
voice over frame problem in a lab setting. I have
a Cisco 2610 and Cisco 3620 connected thru a frame
relay pvc (dlci 600) and I am unable to ping router
to router "after" I implement "vofr cisco" on both
subinterfaces. I put in the traffic shaping/map class
statements and as soon as I put in vofr cisco command
my ospf adj goes down and I lose my dlsw peers on my 2610.
I can not see either router from the "show cdp ne" after
I put in these statements.
Take the statments out and my dlsw peers comes back and my ospf comes back.
The only thing I have noticed is that
once I put these statements in, I start dropping pkts
via the "show frame pvc". My pvc is active and I can see
frame coming across. Just can not ping.
My serial interface looks fine on both. I do not think this is a cloud
problem because once I take
these statements out, everything works fine in terms of pinging. Please
note: my frame cloud is a Cisco 4000 router.
I am able to ping router to router with different ping
patterns (0x0000,0xffff, 0x5555, 0xAAAA, 0x8080) with no
problems when these commands are not in the config. However,
my voice traffic will not pass. My goal is to ping router
router and see my ospf route/dlsw peers (dlsw on 2610) and pass voice
traffic at the same time.
Any help on this would be great. I have been working on this
for about 3 hrs. I am a rookie. Please note: for grins I reloaded both
routers and this still did not work.
