Subject: Encapsulation failed issue.
Hi Group,
I am facing a very strange problem my router is connected to Backbone
through a switch. Router and Backbone are in Vlan 300. I was able to
ping
backbone from my router and then i configured RSPAN with Vlan 300 as
source
after that i am not able to ping my backbone, i removed Monitor session
commands and then also i am not able to ping.
After doing debug ip packet i see encapsulation failed messages, to my
understanding it is when the router is not able to resolve the Layer 2
address, my concern is if we are trapped with such situation in real lab
and
we dont have access to Backbone hpow to make it up and running. I have
reloaded the router and switch still not able to ping.
Kindly suggest.
Thanks for the help.
