Speaking of, I had been wondering for some time where folks are using soft-reconfig inbound, vs relying on soft-refresh from neighbors.
If anyone is using it, mind sharing where and motivates it? -Tk -----Original Message----- From: Brandon Applegate <[email protected]> Date: Sun, 23 May 2010 14:07:25 To: <[email protected]> Subject: Re: [c-nsp] asr1k IOS-XE bgp route-map / crash On Sun, 23 May 2010, Brandon Applegate wrote: > We have some asr1k's running full ipv4 BGP (couple of carriers EBGP - IBGP to > our core).
