Configuring MSDP Redistributing Sources Command or Action Purpose Step 3 ip msdp redistribute [list access-list-name] [asn aspath-access-list-number] [route-map map] Example: Device(config)#ip msdp redistribute list 21 Configures which (S,G) entries from the multicast routing table are advertised in SA messages. By default, only sources within the local domain are advertised. • (Optional) list access-list-name— Enters the name or number of an IP standard or extended access list. The range is 1 to 99 for standard access lists and 100 to 199 for extended lists. The access list controls which local sources are advertised and to which groups they send.
• (Optional) asn aspath-access-list-number—Enters the IP standard or extended access list number in the range 1 to 199. This access list number must also be configured in the ip as-path access-list command. • (Optional) route-map map—Enters the IP standard or extended access list number in the range 1 to 199. This access list number must also be configured in the ip as-path access-list command. The device advertises (S,G) pairs according to the access list or autonomous system path access list. Step 4 Use one of the following:
• access-list access-list-number { deny | permit } source [ source-wildcard ] • access-list access-list-number { deny | permit } protocol source source-wildcard destination destination-wildcard Example: Device(config)#access list 21 permit 194.1.22.0 or Device(config)#access list 21 permit ip 194.1.22.0 1.1.1.1 194.3.44.0 1.1.1.1 Creates an IP standard access list, repeating the command as many times as necessary. or Creates an IP extended access list, repeating the command as many times as necessary. • access-list-number—Enters the same number created in Step 2. The range is 1 to 99 for standard access lists and 100 to 199 for extended lists.
• deny—Denies access if the conditions are matched. The permit keyword permits access if the conditions are matched. • protocol—Enters ip as the protocol name. • source—Enters the number of the network or host from which the packet is being sent. Configuring MSDP 10
