Disable Redistribution

The following example disables the redistribution of directly connected routes (5555::0) on SEFOS1. With redistribution disabled, the route to 5555::0 is not visible on switches SEFOS2 and SEFOS3.

1. On SEFOS2, review the route information before disabling redistribution.

   SEFOS 2 SEFOS# show ipv6 route
    
   IPv6 Routing Table  -  6 entries
   Codes : C - Connected, S - Static
           O - OSPF, R - RIP, B - BGP
   C   1111::/112   [1/1]
           via ::, vlan10
   R   2222::/112   [3/120]
           via fe80::221:28ff:fe56:d7a9, vlan40
   R   3333::/112   [2/120]
           via fe80::221:28ff:fe56:d7a9, vlan40
   C   4444::/112   [1/1]
           via ::, vlan40
   R   5555::/112   [2/120]
           via fe80::221:28ff:fe56:d7a9, vlan40
   C   6666::/112   [1/1]
           via ::, vlan10

2. On SEFOS3, review the route information before disabling redistribution.

   SEFOS 3 SEFOS# show ipv6 route
   IPv6 Routing Table  -  7 entries
   Codes : C - Connected, S - Static
           O - OSPF, R - RIP, B - BGP
   R   1111::/112   [3/120]
           via fe80::221:28ff:fe56:d7a9, vlan30
   C   2222::/112   [1/1]
           via ::, vlan20
   C   3333::/112   [1/1]
           via ::, vlan30
   R   3333::/112   [2/120]
           via fe80::221:28ff:fe56:d7a9, vlan30
   R   4444::/112   [2/120]
           via fe80::221:28ff:fe56:d7a9, vlan30
   R   5555::/112   [2/120]
           via fe80::221:28ff:fe56:d7a9, vlan30
   R   6666::/112   [3/120]
           via fe80::221:28ff:fe56:d7a9, vlan30

3. Disable the route redistribution on SEFOS1.

   SEFOS 1 SEFOS# configure terminal
   SEFOS 1 SEFOS(config)# ipv6 route rip 
   SEFOS 1 SEFOS(config-router)# no redistribute connected 
   SEFOS 1 SEFOS(config-router)# exit

4. On SEFOS2, review the route information after disabling redistribution.

   Note that 5555::/112 [2/120] is missing from the output.

   SEFOS 2 SEFOS# show ipv6 route 
   IPv6 Routing Table  -  5 entries
   Codes : C - Connected, S - Static
           O - OSPF, R - RIP, B - BGP
   C   1111::/112   [1/1]
           via ::, vlan10
   R   2222::/112   [3/120]
           via fe80::221:28ff:fe56:d7a9, vlan40
   R   3333::/112   [3/120]
           via fe80::221:28ff:fe56:d7a9, vlan40
   C   4444::/112   [1/1]
           via ::, vlan40
   C   6666::/112   [1/1]
           via ::, vlan10

5. On SEFOS3, review the route information after disabling redistribution.

   Note that 5555::/112 [2/120] is missing from the output.

   SEFOS 3 SEFOS# show ipv6 route
    
   IPv6 Routing Table  -  6 entries
   Codes : C - Connected, S - Static
           O - OSPF, R - RIP, B - BGP
   R   1111::/112   [3/120]
           via fe80::221:28ff:fe56:d7a9, vlan30
   C   2222::/112   [1/1]
           via ::, vlan20
   C   3333::/112   [1/1]
           via ::, vlan30
   R   3333::/112   [3/120]
           via fe80::221:28ff:fe56:d7a9, vlan30
   R   4444::/112   [3/120]
           via fe80::221:28ff:fe56:d7a9, vlan30
   R   6666::/112   [3/120]
           via fe80::221:28ff:fe56:d7a9, vlan30
