BGP4 - neighbor soft reset does not update weights on policy change? bug?
I Have a Cat6k (SUP1A/MSFC2) running IOS 12.1(20)E doing eBGP with several ISPs. BGP sessions have been up and running for quite some time just fine. Recently, I made a change to the neighbor inbound route-maps and removed the "set weight xxx" statements from all route maps, as I no longer want weight attributes applied to these incoming routes. Did a soft clear on the neighbor sessions and -- no change. Routes still are being tagged with the same old weights that are no longer specified in the route maps!
I can add/remove/change local preference values within the same route maps I was manipulating the weights with, do a soft clear, and see the change take effect after the soft clear by looking at the routes installed in the BGP table. Trying this same sequence with weights... -- I get nothing.
Anyone know if this is *designed* behavior, or a bug? I had always understood that a soft clear would refresh *ALL* BGP attributes in the event of a policy change (weights, local preferences, metrics, etc.)
I would rather not do a full session reset (clear) on these sessions if I don't have to.
