Building explicit tunnels is a painful process, especially when you want to build fully meshed tunnels among a large number of routers. AutoTunnel mesh is a features that mesh LSRs automatically, greatly reduce administrative effort.
- Mesh Group - LSRs to mesh automatically
- Membership identified by
- Matching TE Router ID against ACL
- IGP mesh-group advertisment
- Each member automatically creates tunnel upon detection of a member
- Tunnels instantiated from template
- Individual tunnels not displayed in router configuration
