bgpd: display multipath status in "show ip bgp"
The output of "show ip bg" does not show whether and which routes are
installed as multipath routes along the best route:
BGP table version is 0, local router ID is 10.10.100.209
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale, R Removed
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
*>i1.0.0.0/24 10.10.100.1 1 111 0 15169 i
* i 10.10.100.2 1 111 0 15169 i
* i 10.10.100.3 1 111 0 65100 15169 i
This patch adds a new status code that is showing exactly which routes
are used as multipath:
BGP table version is 0, local router ID is 10.10.100.209
Status codes: s suppressed, d damped, h history, * valid, > best, = multipath,
i internal, r RIB-failure, S Stale, R Removed
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
*>i1.0.0.0/24 10.10.100.1 1 111 0 15169 i
*=i 10.10.100.2 1 111 0 15169 i
* i 10.10.100.3 1 111 0 65100 15169 i
The inconsistency in the status code legend ("i - internal" vs. "i internal")
inherent from old IOS was fixed. It had to be touched anyways.
