R0106-HP MSR Router Series Layer 3 - IP Routing Configuration Guide(V7)

481
An MTR policy comprises multiple nodes. Each node, identified by a node number, contains multiple
match criteria. A packet matches the nodes in the ascending order of their numbers. The nodes of an
MTR policy are in an OR relationship. If a packet matches one of the nodes, it matches the MTR policy.
Each node contains a set of if-match and apply clauses.
• if-match—Defines a criterion to match packet attributes. The if-match clauses of a node are in an
OR relationship. If a packet matches one of the if-match clauses, it matches the node.
• apply—Specifies a topology for packets matching the MTR policy node.
IMPORTANT:
A
node must contain both if-match and apply clauses. Otherwise, the topolo
