Hi, i have the floowing scenario,

CUST A-1----PE1----P-----PE2-----CUST A -2--225.1.1.1

I am trying to Ping from CUST A site 1 to site 2 and the reply is successful.

But when try to ping the destination from my PE1 router i dont get replies,

PE1------ping vrf ABC 225.1.1.1

wen i do debug ip mpack... i can see on PE1 that the source of the packet is lo0 of PE1 bc mdt by default take the source interface as the MBGP interface used for connectivity. is there any way i can change this default behaviour? How can i make my ping successful sitting on PE1

Any gud references on this topic will be helpful.

 

How can i change the MDT behaviour not to take the BGP lo interface as the source ?

 

Thanks

Pls post your configs. As for the default MDT behaviour I wish you well. Multicast needs the tunnels to send the multicast traffic. MPLS is not multicast aware thus you need the tunnels to encapsulate the multicast packets so to speak. Cisco is in progress with switching multicast with labels. However as far as I am aware Cisco have it running with PIM as PIM is already defined, Juniper have is working with BGP extensions. So once the propeller heads sort out which way is best (IETF Standard) you will need to use the tunnels :-)

Thanks

James
