Hi to all,
+-------+ eth1 +-------+
| |==========| |
'network 1' ----| A | | B |---- 'network 2'
| |==========| |
+-------+ eth2 +-------+
A and B are routers
# tc qdisc add dev eth1 root teql0
# tc qdisc add dev eth2 root teql0
# ip link set dev teql0 up
On router A:
# ip addr add dev eth1 10.0.0.0/31
# ip addr add dev eth2 10.0.0.2/31
# ip addr add dev teql0 10.0.0.4/31
On router B:
# ip addr add dev eth1 10.0.0.1/31
# ip addr add dev eth2 10.0.0.3/31
# ip addr add dev teql0 10.0.0.5/31
The above has been quoted from LARTC HOWTO. I would like to know the
following things:
1) Are the 10.0.0.0/31, 10.0.0.2/31, 10.0.0.3/31...different networks? Are
the devices eth1, eth2 and teql0 on each router part of 3 different
networks?
2) What is the reason for doing the "/31" thing? CAn't we use network
addresses such as 192.168.0.0/24, 192.168.10.0/24 and so on for the
devices eth1, eth2 and teql0?
Warm regards,
Visham
