Configuring IPv6 MBGP
Setting the maximum number of multicast routes
supported
The BigIron RX supports up 1024 – 153,600 multicast routes.
NOTE
This procedure requires a software reload to place the change into effect.
To increase the maximum number of multicast routes supported on the device, enter commands
such as the following.
BigIron RX(config)# system-max multicast-route 12000
BigIron RX(config)# write memory
BigIron RX(config)# end
BigIron RX# reload
These commands increase the maximum number of multicast routes supported, save the
configuration change to the startup-config file, and reload the software to place the change into
effect.
Syntax: [no] system-max multicast-route <num>
The <num> parameter specifies the number of multicast routes and can be from 1024 – 153,600.
Enabling IPv6 MBGP
To enable IPv6 MBGP, you must enable PIM SM or DM and IPv6 BGP. Enter commands such as the
following.
BigIron RX> enable
BigIron RX# configure terminal
BigIron RX(config)# ipv6 router pim
BigIron RX(config-ipv6-pim-router)# interface ethernet 1/1
BigIron RX(config-if-e1000-1/1)# ipv6 address 3001::1
BigIron RX(config-if-1/1)# ipv6 pim
BigIron RX(config-if-1/1)# exit
BigIron RX(config)# router bgp
ipv6BGP: Please configure 'local-as' parameter in order to enable ipv6BGP.
BigIron RX(config-bgp)# local-as 10
The commands in this example configure PIM DM globally and on port 1/1, then enable BGP4.
Once you enable PIM DM or PIM SM both globally and on the individual RPF interfaces, and enable
BGP4, support for MBGP is automatically enabled.
Once MBGP is enabled, MBGP parameters are configured under the IPv6 multicast address family.
Enter the following command to enter the IPv6 multicast address family level.
BigIron RX(config-bgp)#address-family ipv6 multicast
BigIron RX(config-bgp-ipv6m)#
Syntax: address-family ipv6 multicast l unicast
Adding IPv6 MBGP neighbors
To add an MBGP neighbor, enter a command such as the following.
BigIron RX(config-bgp-ipv6m)# neighbor 3001::1 remote-as 44
