Ipv6 Frame Relay Configuration

Mathav27

Level 1

Hello, I am trying to configure a static frame relay with the below commands:

Outside_Router(config-if)#frame-relay map ipv6 2001:DB8:3EF:30::1 201 broadcast

Main_Router(config-if)#frame-relay map ipv6 2001:DB8:CCC::1 102 broadcast

I am not sure why but the configuration is not working. I have attached my packet tracer here. Can anyone help me on this

Hi @Mathav27 ,

The two serial interfaces connected via frame relay need to be part of the same IPv6 subnets. You could do the following:

Outside_Router:

int se0/0/0

ipv6 address 2001:db8:3ef:30::2/64

frame-relay map ipv6 2001:DB8:3EF:30::1 201 broadcast

Main_Router:

int se0/1/1

ipv6 address 2001:db8:3ef:30::1/64

frame-relay map ipv6 2001:DB8:3EF:30::2 102 broadcast

So, Ive tried changing the ip address to be be part of same subnet by setting the ip address as follows:

Outside_Router:

int se0/0/0

ipv6 address 2001:db8:3ef:31::1/64

frame-relay map ipv6 2001:DB8:3EF:30::1 201 broadcast

Main_Router:

int se0/1/1

ipv6 address 2001:db8:3ef:30::1/64

frame-relay map ipv6 2001:DB8:3EF:31::1 102 broadcast

 

I modified in such way because that is the requirement for the project. So, after changing it still it seems not working. Ive attached the modified packet tracer file

Hi @Mathav27 ,

It does not work because the two devices are not on the same subnet still. The subnet is a /64, so the first 64 bits have to match, which is not the case.

2001:db8:3ef:31::1/64

2001:db8:3ef:30::1/64
