Hi,
I've set up the config shown in Halibi pg 326. The BGP table for RTA is
shown below. My question is, where does the metric value of 11 come from ?
How is it calculated ? The routes that show a metric of 11 are locally
originated (as can be seen from their weight), but the router has determined
the next hop to be another router within the AS - ie RTF. This is fine, but
I dont understand where the metric value came from.
Halabi's book shows these routes with a metric of 20. Either way I'de be
interested in how local metrics are determined, as opposed to being set in
route maps.
BGP table version is 8, local router ID is 172.16.220.1
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal
Origin codes: i - IGP, e - EGP, ? - incomplete

The configs can be seen in Halibi's book pg 327-329
