IP Forward MIB

The Juniper Networks enterprise-specific IP Forward MIB, whose object identifier is {jnxMibs 38}, extends the ipCidrRouteTable in the IP Forwarding Table MIB (as defined in RFC 2096) to include a tunnel name when the next hop is through an RSVP-signaled LSP.

This MIB adds an jnxIpCidrRouteTunnelName attribute to the ipCidrRouteTable. The attribute exists for each entry in the ipCidrRouteTable. (One entry in the ipCidrRouteTable represents each route in inet.0). If the route's next hop is an RSVP-signaled MPLS LSP, the new attribute contains the LSP name. If the route's next hop is not an RSVP-signaled MPLS LSP, the new attribute is defined as null.

The attribute's name is jnxIpCidrRouteTunnelName. Its object identifier (OID) is 1.3.6.1.4.1.2636.3.38.1.1.1. As with any SNMP attribute, an index is appended to the OID to form the instance identifier. Because this attribute augments the ipCidrRouteTable, the index is identical to that used in the ipCidrRouteTable. The index is formed by concatenating destination address, subnet mask, ToS byte, and next hop.
