Current code has an inconsistent behavior with redistribute routes.
Suppose you have a kernel route that is being read w/ a distance
of 255:
eva# show ip route kernel
Codes: K - kernel route, C - connected, S - static, R - RIP,
O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP,
T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP,
F - PBR, f - OpenFabric,
> - selected route, * - FIB route, q - queued, r - rejected, b - backup
t - trapped, o - offload failure
K>* 0.0.0.0/0 [0/100] via 192.168.161.1, enp39s0, 00:06:39
K>* 4.4.4.4/32 [255/8192] via 192.168.161.1, enp39s0, 00:01:26
eva#
If you have redistribution already turned on for kernel routes
you will be notified of the 4.4.4.4/32 route. If you turn
on kernel route redistribution watching after the 4.4.4.4/32 route
has been read by zebra you will never learn of it.
There is no need to look for infinite distance in the redistribution
code. Either we are selected or not. In other words non kernel routes
with an 255 distance are never installed so the checks were pointless.
So let's just remove the distance checking and tell interested parties
about the 255 kernel route if it exists.

FRRouting
FRR is free software that implements and manages various IPv4 and IPv6 routing protocols. It runs on nearly all distributions of Linux and BSD and supports all modern CPU architectures.
FRR currently supports the following protocols:
- BGP
- OSPFv2
- OSPFv3
- RIPv1
- RIPv2
- RIPng
- IS-IS
- PIM-SM/MSDP
- LDP
- BFD
- Babel
- PBR
- OpenFabric
- VRRP
- EIGRP (alpha)
- NHRP (alpha)
Installation & Use
For source tarballs, see the releases page.
For Debian and its derivatives, use the APT repository at https://deb.frrouting.org/.
Instructions on building and installing from source for supported platforms may be found in the developer docs.
Once installed, please refer to the user guide for instructions on use.
