Manual Routing
When a Tunnel is created, the route has not been defined thus the Path contains a “Hole”. The user can select Manual, Automatic or Advanced Routing to complete the route.
The Manual Routing window returns a list of possible MPLS links with enough available bandwidth to reach the Next-Hop MPLS node. The user has to manually select each “Hop” until the path is complete.
The listed next-hop links must fulfill several constraints:
• the links must have enough Available bandwidth
• to prevent loops, the links leading to nodes already in the path are not listed. This implies that a link can only be used once.
