OTV over MPLS Network

[mhuaynate]

Hi,

My friends i am configuring a OTV between two DataCente over MPLS network, but this does not working. I need to konw if there is some consideratión o enable some special feature in the MPLS network. I am using only one VDC in each site. The comunication between router is working fine, both Nexus 7K dont achieve built adjacency.

NK701# show otv

I don't know the answer, but I think it is bad that "Site vlan : 999 (down)".  I would resolve that first.

HI,

when i do this configuration in both site my OTV working fine

interface Overlay1
otv join-interface Ethernet3/1
otv extend-vlan 10
otv use-adjacency-server 10.1.1.5 unicast-only
otv adjacency-server unicast-only
no shutdown

But when i do this configuration doesnt work, i dont kown why ?

interface Overlay1
otv join-interface Ethernet3/1
otv control-group 224.1.1.1
otv data-group 232.1.1.0/24
otv extend-vlan 10
no shutdown

Maybe i need to enable same feature in OTV or MPS network.

Thank,

M.

There are a few basic configs that one has to do on the OTV VDC like defining the igmp version 3 on the join interface. The multicast mode assumes that the core is multicast enabled and capable of forwarding the multicast traffic. The join interface is both a source and receiver so as long as the S,G or relevant states are created on the first hop router, the multicast traffic will flow correctly. 

If you reconfigure the OTV setup, the first thing to do is check the S,G state and see if you see 2 sources since u have 2 OTV VDCs only. Also Check the OIF is pointing in the right direction for teh respective sources. The source will be the join IP of each VDC.

Hope this helps.
