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;
}


}


}


}


}
