Sharing IPsec Connections

On CSR, the user can configure multiple GRE tunnels to use the same IPsec connection.

The user needs to add an extra shared keyword after the profile name on every tunnel interface that is to be shared.
switch(config)#interface Tunnel0
switch(config-if)#tunnel protection ipsec profile vrouter-ikev2-ipsec-profile shared
switch(config-if)#exit
