[j-nsp] NG-MVPN flow prob

[Ahsan Khan]

Hi,

I am working on NG-MVPN, my topology is as under:



– CE1 – PE1 – P – PE2 – CE2 –

                  |_______|

                       |

         Routing instance “test”



CE1: Cisco 3845                           (Source IP: 192.168.1.2)

PE1: J6350 (JUNOS 8.5R3.4)         Lo0: 3.3.3.3

P: M7i (JUNOS 8.5R3.4)                Lo0: 1.1.1.1

PE2: M7i (JUNOS 8.5R3.4)            Lo0: 2.2.2.2

CE2: Cisco 2800                           (Source IP: 192.168.2.2)



I am using p2mp rsvp based tunnel (default template). Everything is working
fine when a source attached with CE2 (connected with Juniper M7i) starts
sending multicast traffic, receiver at CE1 (Connected with J6350) end
receives it perfectly.

Problem occurs when CE1 (Connected with J6350) source starts sending
multicast traffic but CE2 (Connected with M7i) receiver doesnot receive it

Type 1 and 7 routes are present in route table test.mvpn but traffic is
unable to flow from PE1-PE2.



Anyone else faces this issue before or am I missing something here? (“Show
route table test.mvpn” is attached )

I can share configurations if it helps. Any assist will be appreciated.
