Hi I have project where network looks like this: IPTV source | 7600_1------------ | | | | 7600_2 | | | | | 7600_3------------- | IPTV distribution switches (~20 VLANs)
I'm currently using PIM static joins on first 7600 next to the source and classic PIM spare-mode (ip pim spare-mode) sessions between rest 7600 and 'pim passive' from 7600 to IPTV distribution switches. First 7600 is my RP. My question is how I can provide redundancy in this network. I had issue, when link between 7600_1 and 7600_2 was down, and traffic switched to link 7600_1--7600_3. IPv4 works without problem as OSPF use backup path. But how deal with PIM and multicasts ? Intergrate MSDP or other protocol ? Any recommendations ? I think about creating xconnect (L2VPN over MPLS) from first 7600_1 to 7600_3 and put additional Cat6500 on the end as PIM box.
