Configure Multi-area SPB Layer 2 Multicast Snooping Redistribution

About this task

Perform this procedure to configure Multi-area SPB layer 2 multicast snooping redistribution for specific I-SID values or a specific I-SID list.

Procedure

  1. Enter IS-IS Router Configuration mode:

    enable

    configure terminal

    router isis

  2. Create the Multi-area SPB layer 2 snooping multicast redistribution for a specific I-SID or I-SID list:

    multi-area l2 redistribute snoop-multicast {home-to-remote | remote-to-home} {i-sid <1-16777215> | isid-list WORD<1-32>}

  3. Optional: Configure a route policy to govern the redistribution:

    multi-area l2 redistribute snoop-multicast {home-to-remote | remote-to-home} {i-sid <1-16777215> | isid-list WORD<1-32>} route-map WORD<1-64>

  4. Enable the Multi-area SPB layer 2 snooping multicast redistribution instance:

    multi-area l2 redistribute snoop-multicast {home-to-remote | remote-to-home} {i-sid <1-16777215> | isid-list WORD<1-32>} enable

  5. Verify the Multi-area SPB layer 2 snooping multicast redistribution configuration:

    show isis multi-area l2 redistribute snoop-multicast

  6. Apply the Multi-area SPB layer 2 snooping multicast redistribution:

    isis multi-area l2 apply redistribute snoop-multicast [home-to-remote | remote-to-home]

Examples

Configuring Multi-area SPB layer 2 home to remote multicast snooping redistribution:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#router isis

Configuring Multi-area SPB layer 2 home to remote multicast snooping redistribution for I-SID 1100:

Switch:1(config-isis)#multi-area l2 redistribute snoop-multicast home-to-remote i-sid 1100
Switch:1(config-isis)#multi-area l2 redistribute snoop-multicast home-to-remote i-sid 1100 
route-map test
Switch:1(config-isis)#multi-area l2 redistribute snoop-multicast home-to-remote i-sid 1100 
enable

Configuring Multi-area SPB layer 2 home to remote multicast snooping redistribution for I-SID list List1:

Switch:1(config-isis)#multi-area l2 redistribute snoop-multicast home-to-remote isid-list 
List1
Switch:1(config-isis)#multi-area l2 redistribute snoop-multicast home-to-remote isid-list 
List1 route-map test
Switch:1(config-isis)#multi-area l2 redistribute snoop-multicast home-to-remote isid-list 
List1 enable

Verifying the Multi-area SPB layer 2 home to remote multicast snooping redistribution configuration:

Switch:1(config-isis)#show isis multi-area l2 redistribute snoop-multicast

Applying the Multi-area SPB layer 2 home to remote multicast snooping redistribution:

Switch:1(config-isis)#isis multi-area l2 apply redistribute snoop-multicast home-to-remote
