L3 Failure Paths
Layer 3 paths can be private or internet
paths, VPN, or standard VPNs. There is a Layer 3 failure on all
other paths and there is no way to reach the WAN side destination
optimally or sub-optimally.
A path that is configured in the Layer 3 failure
paths list is considered only in the following conditions:
- Condition 1
- All active and backup paths are up and available, but Layer 3 is unreachable.
- Layer 3 failure paths are configured and up.
- At least one Layer 3 failure path is Layer 3 reachable.
- Condition 2
- All active and backup paths are down or routes on both paths do not exist. For example, direct on public-1 and public-1 do not exist.
- Layer 3 failure paths are configured and are up.
- Condition 3
- Network asymmetry.
