What is the meaning of the "tag" value in "Zebra send: IPv4 route add" output log entry?
Hi there.

I enabled some debug commands in my quagga BGP router (lab environment) and
I'm seeing entries like that:

2020/12/22 15:40:07.868882 BGP: Zebra send: IPv4 route add X.X.X.X/Y
nexthop X.Y.W.Z metric 0 tag 1 count 1
2020/12/22 15:47:12.028541 BGP: Zebra send: IPv4 route add X.X.X.X/Y
nexthop A.B.C.D metric 0 tag 1979908097 count 1

What is the meaning of the tag in the output? Sometimes it has values like
0 or 1, but other times the value is 1979908097 or things like this.
