Configuring a Connectionless Network Services Static Route

Connectionless Network Services (CLNS) is an ISO Layer 3 protocol that uses network service access point (NSAP) reachability information instead of IPv4 prefixes.You can configure a static route for CLNS networks.

NOTE: CLNS is supported for J-series Services Routers only.

To configure a CLNS static route, include the following statements:

rib (iso.0 | instance-name.iso.0)

    static {

        route nsap-prefix {

            next-hop (interface-name | iso-net);

            qualified-next-hop (interface-name | iso-net) {

                metric metric;

                preference preference; 

            }

        }

    }

}

For a list of hierarchy levels at which you can configure these statements, see the CLNS statement summary sections in the J-series Services Router Advanced WAN Access Configuration Guide.

Specify the iso.0 routing table option to configure a primary instance CLNS static route. Specify the instance-name.iso.0 routing table option to configure CLNS static route for a particular routing instance. Specify the route nsap-prefix statement to configure the destination for the CLNS static route. Specify the next-hop (interface-name | iso-net) statement to configure the next hop, specified as an ISO network entity title (NET) or interface name. Specify the qualified-next-hop (interface-name | iso-net) statement to configure the qualified next hop, specified as an ISO network entity title or interface name.

Example: Configuring a Static CLNS Route

Configure a static CLNS route with an NSAP of 47.0005.80ff.f800.0000.ffff.ffff:

[edit]

routing-options {

    rib iso.0 {

    static {

         iso-route 47.0005.80ff.f800.0000.ffff.ffff next-hop

            47.0005.80ff.f800.0000.0108.0001.1921.6800.4212;

         iso-route 47.0005.80ff.f800.0000.0108.0001.1921.6800.4212 next-hop

            t1-0/2/2.0;

        iso-route 47.0005.80ff.f800.0000.eee {

        qualified-next-hop 47.0005.80ff.f800.0000.0108.0001.1921.6800.4002 {

            preference 20;

            metric 10;

         }

    }

    }

}
