[c-nsp] ES20, VPLS & netflow problem

[Geir Jensen]

Hello,

I don't have a solution for the netflow problem....
However we are running a 7600/Sup720/ES20/12.2(33)SRB2 - based network, 
and Dmitry's vpls config got me curious.

I notice that the vpls is terminated at layer 3 (ip address x.x.x.x under vlan30), and
I wonder if this configuration requires any special hardware?

Also, does any of you have a pointer to any documentation for this kind of configuration?
On cco, I can only find examples where the VPLS is a (layer2)service connecting customers, and
no examples where the VPLS is terminated at layer3 at the service provider.


Rgds,

Hello,

We have configuration with 2 ciscos 76xx/SUP720 connected together via
10Gb ports on ES20 (Ethernet Services) cards.
MPLS is there. Now we need to make VPLS vlan between them (for BGP full
table). We are exporting netflow information version 5 to the collector.
When traffic goes directly via 10G ports (routed) everything is OK, but 
if we reroute traffic via VPLS VLAN, there is no netflow information
exported about traffic entering the router via this vlan. Netflow 
information about every other traffic  (including traffic which enters 
throught normal SVI interfaces) is appears as usualy.


IOS 12.2(33)SRB2

Is this bug or feature? Here is part of my configuration:


[..]

no mls flow ipv6
mls nde sender version 5
mls qos
