Hi, I am trying to configure OSPF changing the loopback interfaces of my
XORP routers. I have not found how to do with Xorpsh therefore I have
done with ifconfig linux command. But when I try to run my config.boot
file with the OSPF configuration it fails because XORP still thinks that
the loopback address is 127.0.0.1, here is the trace of the error:
# xorp_rtrmgr
[ 2009/05/04 17:53:43 ERROR xorp_rtrmgr:5389 LIBCOMM +312 comm_sock.c
comm_sock_bind4 ] Error binding socket (family = 2, my_addr = 127.0.0.1,
my_port = 19999): Cannot assing requested address
[ 2009/05/04 17.53.43 ERROR xorp_rtrmgr:5389 RTRMGR +243 main_rtrmgr.cc
run ] Cannot assign requested address: a finder may already be running.
Here is my config file is:
interfaces {
interface eth1 {
vif eth1 {
address 10.129.0.3 {
prefix-length: 24
}
}
}
}
fea {
unicast-forwarding4 {
disable: false
}
}
protocols {
ospf4 {
router-id: 192.168.0.1
area 0.0.0.1 {
interface eth1 {
vif eth1 {
address 10.129.0.3 {
}
}
}
}
}
}
When I again put with ifconfig the loopback to 127.0.0.1 it doesn't
fail. I want to define my loopback address as the router-id,
192.168.0.1, how can I change the property my address? And how can I
change the loopback address with XORP? Thanks for everything,
Alejandro Berna
