[LARTC] does metric in route works?

[Poltorak Serguei]

Hello

I would like to know how does metric work for now.
I'm trying to use it for failover. if my nexthop (gateway) is down i
want another route with bigger metric to be used. for now all in vain. :(
are there any implementation of metric in current routing mechanism??

Re: [LARTC] routing broadcast messages

Hello

but packets  are going To their subnetwork. then m.n.o.w sends packet to
a.b.c.255 gateways other than a.b.c.1 doesn't know that a.b.c.255 is a
broadcast. it's only a.b.c.1 (m.n.o.p) who discards the packet

may be I should redraw my pic.
  a.b.c.0/24,brd+ -[ a.b.c.1, m.n.o.p ]-m.n.o.w
   ---pings are going in that direction

So, packets are going TO their subnet.

Any idea???

thanks,

[LARTC] routing broadcast messages

[Poltorak Serguei]

Hello.

I would like to route broadcast messages.
For now, if I ping a.b.c.255 from m.n.o.w the packet is passing through
each router, except the last, a.b.c.1 (m.n.o.p, other external address)
and only he replys to that packet, but not from a.b.c.1, he does it from
m.n.o.p address (logic, it's the address of the output interface).

simple pic.   a.b.c.0/24--[ a.b.c.1, m.n.o.p ]---m.n.o.w

How can i fix this problem??
It could be very cool tool to know, how many hosts are up in your netS.
Combined with VPN from FreeS/WAN (he transports brdcast as other ip
trafic) makes administration easier.

thanks for help.
