RE: secondary ip address on e0? [7:28027]

Configuring Sub-interfaces on a c1603
What could possibly go wrong??
It looked so easy in the book.
Does this mean I must use secondary IP addresses on the e0,
and sub-interfaces only on s0?
Eg.,
#int e0
ip address [i.p.address] [subnet.mask] secondary
#int s0.1
ip address [i.p.address] [subnet.mask]

In the book it said that "secondary" IP addresses were being phased out in
the newer IOS.

Help please...

Rustyb#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
rustyb(config)#int e0
rustyb(config-if)#ip address 193.9.56.1 255.255.255.0
rustyb(config-if)#int e0.1
rustyb(config-subif)#ip address 192.9.200.1 255.255.255.0

Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10 or ISL vLAN.

rustyb(config-subif)#exit
rustyb(config)#int e0
rustyb(config-if)#no shut
rustyb(config-if)#
rustyb(config-if)#
rustyb(config-if)#int e0.1
rustyb(config-subif)#ip address 192.9.200.1 255.255.255.0

RE: secondary ip address on e0? [7:28027]

Hi Anil,
There appears to be a conflict here.
Is it Secondary addresses ( ie: 2 ip addresses on the same physical port) or
subinterfaces.

If you need secondary addressing use something like this

conf t
int fas0/0
ip address 10.128.10.1 255.255.255.0 
ip address 172.16.16.1 255.255.255.0 secondary

If you want subinterfaces you will need to set the encapsulation of each
subinterface:

conf t
int fastethernet 0/0.1
encapsulation  

Hope this helps matters


Regards
Richard
