I will be doing my first BGP config from scratch next week and needed some suggestions from the BGP gurus here..
I will have 2x 3640 routers connected to 3 different upstreams. I will call them Platinum, Gold and Silver based on the preference of use.
The Platinum will be the preferred route out and in. The gold would be next and the silver would be last.
See the attached.. Both 3640 routers will run BGP partial routes only (connected networks on the upstreams). They will also run VRRP to provide failover. The switches that handle the upstream coming in will be L2 only and acting as a transciever to the fibre links converting them to copper.
What is the best way to setup BGP to use the Platinum only unless it fails, then the gold and then silver? Minimal traffic over the gold and silver would be allowed, but would prefer to direct 99% of the traffic out to the 1gbps link via Platinum.
The larger switches are 5505 with a single SUP3 and RSM for VLAN termination. They will be running HSRP for redundancy for the server vlans below it (not pictured).
Any suggestions would be appreciated.
