Summary on the configuration of PIM based on basic routing knowledge

PIMIS short for Protocol Independent Multicast Protocol-Independent Multicast. It indicates that static routing or any unicast routing protocols, including RIP, OSPF, IS-IS, and BGP, can be used) the generated unicast route table provides a route for IP multicast. Multicast routes are irrelevant to the unicast routing protocol. You only need to generate a route table entry through the unicast routing protocol.

To configure a vro as a member of the HSRP backup group, run the following command in Interface Configuration Mode:

Router (config-if) # standby group-number ip address-address

In the interface configuration mode:

Router (config-if) # standy group-number preempt

The access time and retention time parameters are configurable:

Router (config-if) # standy group-number timers hellotime holdtime

Configure HSRP tracking:

Router (config-if) # standy group-number track type-number interface-priority

To display the status of the HSRP router:

Router # show standby type-number group brief

Run the show ip igmp command to determine the queried server.

Start IP Multicast Route Selection:

Router (config) # ip muticast-routing

PIM on the startup interface:

Dalllasr1> (config-if) # ip pim {dense-mode | sparse-dense-mode}

Start the PIM in dense mode:

 
 

  
  
router# ip multicast-routing 
  
  
router# interface type number 
  
  
router# ip pim sparse-dense-mode 
 
 

Verify the PIM Configuration:

Dallasr1> # show ip pim interface [type number] [count]

Display PIM neighbors:

Dallasr1> # show ip neighbor type number

To configure the RP address, run the following command:

Dallasr1> # ip pim rp-address ip-address [group-access-list-number] [override]

Select a default RP:

Dallasr1> # ip pim rp-address

Advertise the RP and its service group scope:

Dallasr1> # ip pim send-rp-announce type number scope ttl group-list access-list-number

Advertise the RP address for the management range group:

 
 

  
  
dallasr1># ip pim send-rp-announce ethernet0 scope 16 group-list1 
  
  
dallasr1># access-list 1 permit 266.0.0.0 0.255.255.255 
 
 

Set an RP image Proxy:

Dallasr1> # ip pim send-rp-discovery scope ttl

Verify the image from the group to the RP:

 
 

  
  
dallasr1># show ip pim rp mapping 
  
  
dallasr1># show ip pim rp [group-name|group-address] [mapping] 
 
 

On the router interface, use the command ip multicast ttl-threshold ttl-value to set the TTL threshold value:

Dallasr1> (config-if) # ip multicast ttl-threshold ttl-value

Use show ip pim neighbor to display the PIM neighbor table.

Each record in the multicast communication route table is displayed:

Dallasr1> show ip mroute [group-name | group-address] [scoure] [summary] [count] [active kbps]

To record all IP multicast packets accepted and sent by a vro:

Dallasr1> # debug ip mpacket [detail] [access-list] [group]
