Routes from BGP and OSPF not Installed in the Routing Table
Issue
The route table entries for BGP and OSPF routes are missing from the routing table. For example:
frr# show ip bgp
BGP table version is 0, local router ID is 10.4.4.4
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

Environment
- Cumulus Linux, all versions
Cause
The Zebra daemon is not running. The Zebra daemon does not install routes, learned from routing protocols, into the routing table.
Resolution
Edit
/etc/frr/daemonsand set thezebrakeyword to yes.cumulus@switch:~$ sudo vi /etc/frr/daemons ---------------- zebra=no [change to yes] bgpd=yes ospfd=yes ----------------Restart FRRouting.
