IPV6 – Multicast Lab Tips

  • Enable this using ipv6 cef, ipv6 unicast-routing and ipv6 multicast routing.
  • The above latter command will enable PIM Sparse-mode on all ipv6 interfaces! Unlike ipv4 you had to do the ip pim sparse-mode on each interface.
  • To join a multicast group use ipv6 mld join-group which is the same as ip igmp join-group.
  • Auto-rp no longer exists. only static and BSR. Same commands used as in IPV4.
  • Configuring the RP will create a GRE tunnel! in ipv4 the router sends a join request to the RP by encapsulating it in a unicast. in IPV6 a GRE tunnel is created instead.
