Can someone help me set up addressing on interface

[hfakoor222]

Lab I am doing has the instructors set up the addressing on the links between the transit routers

However they gave  appendix on how to set it up

the appendix on the bottom says Tr1 and Tr2 are very similar

https://nsrc.org/workshops/2019/mnnog1/riso/networking/routing-security/en/labs/ebgp.html

basically on TR2 f1/1 interface this is the commands

TR2 Router
description Link to TR2 (and to the world)
ip address 100.121.0.0 255.255.255.254 secondary
ip address 10.10.0.235 255.255.255.0
ipv6 address 2001:18::/127
ipv6 address 2001:DB8:100::235/64

and so I just modified it a little bit for the addressing on TR1 router

TR1 Router
interface f1/1
description Link to TR2 (and to the world)
ip address 100.121.0.1 255.255.255.254 secondary
ip address 10.10.0.236 255.255.255.0
ipv6 address 2001:18::1/127
ipv6 address 2001:DB8:100::236/64

IIt's pinging fine

I'm asking for opinions if there's any potential dangers in the way I've addressed or anything I can improve on

Addressing looks fine but it is not clear why you need two sets of IPv4 and IPv6 addressing per interface.

I removed some on the interfaces pointed to the AS from the transit routers, I'm still playing with it

Hi

 No danger and if it is ping fine, you did it right.
