Basics:
R1- eth01- IPv6 — 2001:db8::1/64 ------------------ eth1 2001:db8::2/64 R2
PtP Scenario between routers above, Now for my lan is something like this:
((Router 1 )) eth02 ((Advertise )) 2001:db3::1/64 -------------- My pc. / ((Router 2 )) eth02 ((Advertise)) 2001:db9::1/64.
I get my V6 Adresses on my computers, and so, I can ping Their Respective Eth1 Adresses from any device on the Eth02 of each routers, no problem there, The thing is, I Cant ping/reach from R1 eth1 2001:db8::2, and vice versa.
Unless I add a route aiming for eth2 adres space of each router, Only then I can succesfully reach Each other 2001:db8::/64 adress.
I know i aint good explaining, here’s direct copy and paste of my config.
/ipv6 address
add address=2001:db3::1 interface=ether2
add address=2001:db8::1 advertise=no interface=ether1
/ipv6 route
add distance=1 dst-address=2001:db9::/64 gateway=2001:db8::2
