Configuring a Destination Profile for Dynamic GRE Tunnels

1. Configure a destination profile for GRE.

   host1(config-dest-profile)#gre destination profile kanata1 virtual-router vr1

2. Set the source address for the tunnel.
   host1(config-dest-profile)#tunnel source 1.1.1.1
3. Set the destination address for the tunnel.
   host1(config-dest-profile)#tunnel destination subnet 10.0.0.0 255.0.0.0
4. (Optional) Set the maximum transmission unit (MTU) size for the tunnel.
   host1(config-dest-profile)#tunnel mtu 10240
5. (Optional) Configure an IP profile with parameters that are used to stack an upper IP interface over a dynamic GRE tunnel.
   host1(config-dest-profile)#profile ip-kanata
6. (Optional) Enable error checking across a GRE tunnel.
   host1(config-dest-profile)#tunnel checksum
7. (Optional) Enable sequence number generation for a GRE tunnel.
   host1(config-dest-profile)#tunnel sequence-datagrams
8. (Optional) Enable IPsec transport mode.
   host1(config-dest-profile)#enable ipsec-transport
9. (Optional) Create a multicast VPN tunnel.
   host1(config-dest-profile)#tunnel mdt profile kanata-mdt
