[c-nsp] ASR Netflow Query

[Roddy Strachan]

Hey all,

Been playing around with an ASR1004 for terminating L2TP sessions.

One thing I¹ve noticed that shows up in a cache flow output is the following
:

gi0/1/0.1     x.x.x.x  RP0_Punt      224.0.0.5       59 0000 0000  17
gi0/1/0.1     x.x.x.x  RP0_Punt      224.0.0.5       59 0000 0000  17
gi0/1/0.1     x.x.x.x  RP0_Punt      224.0.0.5       59 0000 0000  608
gi0/1/0.1     x.x.x.x  RP0_Punt      224.0.0.5       59 0000 0000  17
gi0/1/0.1     x.x.x.x  RP0_Punt      224.0.0.5       59 0000 0000  198

That in turn fills up our flow files on the collectors with data looking
like this :

1221452253 x.x.x.x x.x.x.x 0 224.0.0.5 0 12740 2 0 0 0
1221452255 x.x.x.x x.x.x.x 0 224.0.0.5 0 11648 2 0 0 0
1221452259 x.x.x.x x.x.x.x 0 224.0.0.5 0 12740 2 0 0 0
1221452260 x.x.x.x x.x.x.x 0 224.0.0.5 0 12740 2 0 0 0


I don¹t see this type of behaviour on the 7200/7300 platform doing the same
type of thing for L2TP sessions.

>From what I understand its a multicast broadcast for OSPF (correct me if I¹m
wrong).

Is there anyone to turn this off so it doesn¹t show up in the  ³sh ip cache
flow² output ? Therefor not filling up out collector with unnecessary
information

Thanks
