Prerequisites
Figure: Example configuration shows an example GTM configuration.
Figure: Example configuration
where:
routers A and F are CE routers
routers B, C, D, and E are MSR routers in the core network
the multicast source is at x4
the multicast receivers are at x1, x2, and x3
Perform the following steps to configure GTM:
Procedure
-
Configure PIM parameters for GTM.
The following output displays the PIM configuration.
*B:Dut-D>config>router>pim# info ---------------------------------------------- interface "intf_to_B" shutdown exit interface "intf_to_E" shutdown exit apply-to all rp static address 10.100.1.1 group-prefix 224.0.0.0/4 exit exit bsr-candidate shutdown exit rp-candidate shutdown exit exit gtm auto-discovery default exit no mc-ecmp-balance no shutdown ---------------------------------------------- *B:Dut-D>config>router>pim# -
Configure the GTM parameters.
The following output displays the GTM configuration.
*B:Dut-D>config>router>gtm# info ---------------------------------------------- mvpn provider-tunnel inclusive rsvp lsp-template "IpmsiTmpl" no shutdown exit exit selective rsvp lsp-template "SpmsiTmpl" no shutdown exit maximum-p2mp-spmsi 4000 data-threshold 224.0.0.0/4 1 exit exit ---------------------------------------------- *B:Dut-D>config>router>gtm# -
Configure a route policy for BGP.
The following output displays the route policy configuration.

Configure BGP parameters for GTM.
The following output displays the BGP configuration on router D.
*B:Dut-D#configure router bgp *B:Dut-D>config>router>bgp# info ---------------------------------------------- connect-retry 1 multipath 16 export "acceptAllBgp" router-id 10.20.1.4 rapid-withdrawal rapid-update mvpn-ipv4 mdt-safi mvpn-ipv6 mvpn-vrf-import-subtype-new best-path-selection ignore-nh-metric exit group "none" family ipv4 ipv6 mvpn-ipv4 mvpn-ipv6 label-ipv4 label-ipv6 next-hop-self local-address 10.20.1.4 neighbor 10.20.1.2 peer-as 200 exit neighbor 10.20.1.3 med-out 100 peer-as 200 exit neighbor 10.20.1.5 med-out 100 peer-as 200 exit exit no shutdown ----------------------------------------------The following output displays the MVPN context on router D.
