IPv6
System configuration commands
Use this command to define the maximum number of entries to keep in the Neighbor cache (1024, 2048, 4096, 8192, 16384, 32768).
Use this command to disable IPv6 operation on interface when Duplicate Address Detection fails on Link-Local address.
Use this command to user Layer 4 information for 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, isis, kernel, ospfv3, ripng, static, table
Note
If you choose any as the option that will cause all protocols that are sending routes to zebra.
