fib: Source Address Selection
Type: feature Use the FIB to provide SAS (in so far as it is today) - Use the glean adjacency as the record of the connected prefixes = there's a glean per-{interface, protocol, connected-prefix} - Keep the glean up to date with whatever the recieve host prefix is (since it can change) Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Change-Id: I0f3dd1edb1f3fc965af1c7c586709028eb9cdeac
