Tool : GNS3

Purpose : Understanding Bootstrap BSR Operation for IPv6 multicast

Topology :

Comments:
All router running OSPFv3
All router running PIM-SM
R0 is the Candidate RP with priority 100
R1 is the Candidate BSR
R2 is the Candidate RP and BSR with priority 100
HOST1 join to group FF17:7:77::777
HOST2 and HOST3 sends multicast traffic to FF17:7:77::777

Example configuration for BSR operations

–Set C-RP and C-BSR
!
ipv6 pim bsr candidate bsr 2001::3 priority 100
ipv6 pim bsr candidate rp 2001::3
!

Let’s verify the configuration

R1#show ipv6 pim bsr election
PIMv2 BSR information

BSR Election Information
  Scope Range List: ff00::/8
     BSR Address: 2001::3
     Uptime: 00:17:25, BSR Priority: 100, Hash mask length: 126
     RPF: FE80::CE02:AFF:FE68:0,FastEthernet1/0
     BS Timer: 00:02:03
  This system is candidate BSR
      Candidate BSR address: 2001::2, priority: 0, hash mask length: 126

R2#show ipv6 pim bsr candidate-rp
PIMv2 C-RP information
    Candidate RP: 2001::3 SM
      All Learnt Scoped Zones, Priority 192, Holdtime 150
      Advertisement interval 60 seconds
      Next advertisement in 00:00:19
