Re: [nznog] Multicast traffic replication issue

We use Citybridge as a wellington-auckland transit provider and at one point we had an issue with the OSPF that underpins our BGP and LSPs. The issue wasn't immediately apparent when we commissioned the service but appeared abruptly a few weeks later. The incident report stated that they had to increase the Multicast limit on the transit. Not particularly clear on what limits were in place or why they suddenly became an issue but its pretty clear that there is some multicast manipulation in place. I would suggest taking this back to Citylink again, i'm guessing that getting a man in the middle to test each leg of the transit is not going to happen?
