2 IP-Aliasing:
3 ============
4
5
6 o For IP aliasing you must have IP_ALIAS support included by static
7 linking.
8
9 o Alias creation.
10 Alias creation is done by 'magic' iface naming: eg. to create a
11 200.1.1.1 alias for eth0 ...
12
13 # ifconfig eth0:0 200.1.1.1 etc,etc....
14 ~~ -> request alias #0 creation (if not yet exists) for eth0
15 and routing stuff also ...
16 # route add -host 200.1.1.1 dev eth0:0 (if same IP network as
17 main device)
18
19 # route add -net 200.1.1.0 dev eth0:0 (if completely new network wanted
20 for eth0:0)
21
22 o Alias deletion.
23 Also done by shutting the interface down:
24
25 # ifconfig eth0:0 down
26 ~~~~~~~~~~ -> will delete alias
27
28
29 Alias (re-)configuring
30
31 Aliases are not real devices, but programs` should be able to configure and
32 refer to them as usual (ifconfig, route, etc).
33
34 Relationship with main device
35 -----------------------------
36
37 - the main device is an alias itself like additional aliases and can
38 be shut down without deleting other aliases.
