l2-learning

In the case of central routing and bridging deployments, you need to configure the crb-proxy-mac statement on all the leaf nodes. Use the following configuration to configure crb-proxy-mac CLI statement:

On IPv4:

user@host# set protocols l2-learning crb-proxy-mac family inet mac-address

On IPv6:

user@host#set protocols l2-learning crb-proxy-mac family inet6 mac-address

When IRB is not configured on the leaf devices, to do ARP/ND refresh upon ARP/ND timer (Mac-IP timer) expiration, the configured MAC address is used as the source MAC address.

Specify the aging timer for the Logical Ethernet (LE) bridge-domain. The system learns the MAC address using the next hop (NH) and the bridge-domain (BD), which together form the NHBD. The aging timer, specified in seconds global-le-bridge-domain-aging-time <seconds>, determines how long the system retains the MAC entry in the forwarding table before removing it. Setting a shorter timer removes NHBD entries more quickly.

• Range: 120 to 1000000 seconds

Set the debug context history limit to define how many events the system logs in process memory for debugging. You can specify a value from 0 to 5000000, representing the number of captured events. Each even consumes up to 200 bytes of memory. By default, the system stores 256000 entries to log Layer 2 process events. To disable this feature, set the global-ctx-limit to 0. The system then frees the memory used for context logging and stop logging further events.

• Range: 0 to 5000000 event entries

• Default: 256000 event entries
