When a PBR rule is matched by the packet all entries in the routing table defined by this rule are processed. In case there is no match with these entries, the packet will NOT fall back to the main routing table (eg. to the default route) and will be dropped.
EXAMPLE:In the example bellow, only one entry is configured in the routing table. The ping command will send packets which will match the configured PBR RULE1 but they will not match the routing table entry. Thus, these packets will be dropped:
$ ping 172.16.0.1------------------------------------------------------------------
