• The IPv4 routing is supported only on BDI interfaces, and not supported on physical interfaces (1G, 10G) and port channel interfaces.

• IP addresses cannot be configured on the physical and the port channel interface.

• The maximum number of IPv4 routes that can be learnt is 12,000.

• BDI level IP ACLs are not supported.

• VRRP or HSRP protocols are not supported.

• The maximum number of VRF lite sessions supported are 128.

• BDI statistics is supported only for CPU bounded traffic, for data traffic going over BDI interface will be shown on respective underlying EFP statistics.

• For adding static ARP, it is mandatory that you specify the static MAC address. For example, to configure static ARP, specify the following commands:

  • arp<ip-add> <mac-add> arpa under the config mode.

    mac static address <mac> under the config-if-srv mode.

• The router sends Gratuitous ARP only whenb the BDI interface is brought up, and processes the Gratuitous ARP if it is of the request type.

• IPv6 is not supported.

• IPv4 multicast is not supported.

• IPv4 MIBs are not supported.

• IP-FRR, LFA, segment routing, and policy-based routing are not supported.

• BFD is not supported.

• IP unnumbered is not supported.

• MPLS is not supported.

To configure IP address on BDI interface, enter the following commands:

interface BDI10
ip address 10.10.10.10 255.255.255.0
end

Use the show ip route and show ip route summary commands to verify IP address on BDI interface:

router#show ip route
