Re: MVPN - tunel source address

Hi Tyson,

Thanks for your response. I dismandled the setup for other customer recreate
:)

But I will try it again with the SNMP command. Meanwhile, If it is based on
highest IP address, it should be 24.1.13.1. I am not sure why it chose
24.1.12.1.

I shall try it and let you know.

Thanks,
Nagendra
