No, POS doesn't make sense. I would recommend going for equal cost multipath over parallell gigs to link your 7600, and when you have more than 2-3, then you should be able to justify a SIP-601 and SPA-TENGE for the gsr. Or, if you only run ethernet you can ditch the GSR altogether and do everything in the 7600. Etherchannel on the GSR is not something I would recommend. It's really bad if you're running the older Engine 2 linecards, otherwise it's managable. I still recommend ECMP over Etherchannel, though. -- Mikael Abrahamsson email: [EMAIL PROTECTED] _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
