Configuring Multiprotocol BGP Extensions for IP Multicast

Multiprotocol BGP Configuration Task List

Step 2	Enter the show ip bgp ipv4 multicast summary EXEC command to display a summary of multicast
	database information:
	Router# show ip bgp ipv4 multicast summary
	BGP router identifier 10.0.33.34, local						AS number 34
	BGP table version			is 5,	main routing table version 1
	4	network entries		and 6	paths using 604		bytes of memory
	5	BGP path attribute entries using 260 bytes of memory
	1	BGP AS-PATH entries using 24 bytes of					memory
	2	BGP community entries			using 48 bytes of memory
	2	BGP route-map cache entries using 32 bytes of memory
	0	BGP filter-list		cache	entries using 0		bytes of memory
	BGP activity 8/28			prefixes, 12/0 paths,			scan interval 15 secs
	Neighbor		V	AS	MsgRcvd MsgSent		TblVer	InQ OutQ Up/Down		State/PfxRcd
	10.0.33.35		4	35	624	624	5	0	0 10:13:46	3
Step 3	Enter the debug ip mbgp dampening EXEC command to log the route flap dampening activity:
	Router# debug ip mbgp dampening

BGP: charge penalty for 173.19.0.0/16 path 49 with halflife-time 15 reuse/suppress 750/2000

BGP: flapped 1 times since 00:00:00. New penalty is 1000

BGP: charge penalty for 173.19.0.0/16 path 19 49 with halflife-time 15 reuse/suppress 750/2000

BGP: flapped 1 times since 00:00:00. New penalty is 1000

Step 4 Enter the debug ip mbgp updates EXEC command to log the multiprotocol BGP-related information passed in BGP Update messages:

Router# debug ip mbgp updates

BGP: NEXT_HOP part				1 net 200.10.202.0/24, neigh 171.69.233.49, next 171.69.233.34
BGP: 171.69.233.49				send UPDATE 200.10.202.0/24, next 171.69.233.34, metric 0, path 33			34
19	49	109 65000	297	1239	1800	3597
BGP: NEXT_HOP part				1 net 200.10.228.0/22, neigh 171.69.233.49, next 171.69.233.34
BGP: 171.69.233.49				rcv UPDATE		about 222.2.2.0/24, next hop 171.69.233.49, path 49 109
metric 0
BGP: 171.69.233.49				rcv UPDATE		about 131.103.0.0/16, next hop 171.69.233.49, path 49 109
metric 0
BGP: 171.69.233.49				rcv UPDATE		about 206.205.242.0/24, next hop 171.69.233.49, path 49	109
metric 0

Step 5 Enter the show ip mpacket quality EXEC command to display the quality of Real-Time Transport Protocol (RTP) data based on packets captured in the IP multicast cache header buffer:

Router# show ip mpacket 224.2.163.188 quality

Calculating RTP data quality for 224.2.163.188
