System configuration commands
Use this command to disable IPv4 directed broadcast forwarding on all interfaces.
If set, IPv4 directed broadcast forwarding will be completely disabled regardless of whether per-interface directed broadcast forwarding is enabled or not.
Use this command to define the maximum number of entries to keep in the ARP cache (1024, 2048, 4096, 8192, 16384, 32768).
Use this command to use Layer 4 information for IPv4 ECMP hashing.
Zebra/Kernel route filtering
Zebra supports prefix-lists and Route Mapss to match routes received from other FRR components. The permit/deny facilities provided by these commands can be used to filter which routes zebra will install in the kernel.
Apply a route-map filter to routes for the specified protocol. The following protocols can be used: any, babel, bgp, connected, eigrp, isis, kernel, ospf, rip, static, table
If you choose any as the option that will cause all protocols that are sending routes to zebra.
