Sample host route (BIR/32) configurations
When a Stinger IP2000 receives a packet to a BIR/32 interface, it examines the full 32
bits of the destination address and forwards the packet to the related CPE.
Figure 4-12 shows two bridging DSL CPE devices, each supporting one host. In this
example, the IP hosts have addresses on the same IP network, but that is not a
requirement.
Figure 4-12. BIR/32 configurations
local-address
value is the same for both BIR interfaces. This is
recommended for host routes to the same IP network because it simplifies
configuration of the remote hosts, all of which can point to the same local address as
the gateway.
The following commands configure a BIR/32 interface through the CPE labeled
Bridge-5 in Figure 4-12:
admin> new connection bir-5
admin> set active = yes
admin> set encapsulation-protocol = atm
admin> set ip-options remote-address = 4.4.4.5/32
admin> set ip-options local-address = 4.4.4.1/32
admin> set atm-options atm1483type = aal5-llc
admin> set atm-options vci = 111
admin> set bir-options enable = yes
admin> which -n { 1 2 5 }
Nailed group corresponding to port { shelf-1 slot-2 5 } is 55
admin> set atm-options nailed-group = 55
admin> write -f
