Usage guidelines
Before executing this command, you must enable MPLS L2VPN by using the mpls l2vpn command.
Only SVC MPLS L2VPN supports Soft GRE.
To set up a remote MPLS L2VPN connection between two PEs, you must use MPLS LDP, MPLS TE, or GRE
to set up a public tunnel that carry the VC. You can use Soft GRE to replace the complicated public tunnel
configuration.
After Soft GRE is enabled on a PE, the PE does the following:
• If no public tunnel exists, or the existing public tunnel does not meet the tunnel policy requirements,
the PE uses Soft GRE to create a public tunnel.
Soft GRE encapsulates Layer 2 data packets containing VC labels with a GRE header and IP
header. The source IP address of the IP header is the local LSR ID, and the destination IP address
is the remote PE address.
• If a public tunnel exists, the PE uses the public tunnel to encapsulate packets.
Examples
# Enable Soft GRE.
