Point-to-Point (Router) Network Interface Conﬁguration Screens

Point-to-Point Reachable Nodes

Class A: 001–126

If the link speciﬁed in the Link Name ﬁeld is the only

link conﬁgured for this network interface and is not a

shared dial link, you can enter a “wildcard” symbol by

specifying an “at sign” (@) in place of the IP address.

The @ in this ﬁeld indicates that multiple non-adjacent

point-to-point nodes on this network can be reached via

the link speciﬁed in the link name ﬁeld. (Non-adjacent

links are not allowed to use a shared dial link.) Using

the @ wildcard enables you to conﬁgure this screen only

once for all non-adjacent nodes reachable by the

speciﬁed link. Use the @ only if the link speciﬁed is the

only link for this network interface. The @ must be

left-justiﬁed in the IP internet address ﬁeld. Make sure

you separately conﬁgure the mapping to the adjacent

node from which the non-adjacent nodes can be

reached.

For example, Figure 6-16 shows a point-to-point

network. From node A, all other nodes on the network

must be reached through node B. During conﬁguration

of node A, the @ could be entered to indicate that all

communication to non-adjacent nodes originating from

A must be routed through node B (over Link 1). In

addition to this mapping, one mapping would have to

be conﬁgured at node A: the mapping from node A to

the adjacent node B.

Default value: None
