Parameters

vpn-instance vpn-instance-name: Displays the FIB table for the specified VPN. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If you do not specify a VPN, this command displays the FIB entries of the public network.

ip-address: Displays the FIB entry that matches the specified destination IP address.

mask: Specifies the mask for the IP address.

mask-length: Specifies the mask length for the IP address, the number of consecutive ones in the mask. The value range is 0 to 32.

Usage guidelines

Each FIB entry contains a destination IP address/mask, next hop, and output interface.

If you specify an IP address without a mask or mask length, this command displays the longest matching FIB entry.

If you specify an IP address and a mask or mask length, this command displays the exactly matching FIB entry.
