IP Networking

Hi.. I have problem about connecting two network. First let me tell about my project. I use Quagga to build up IPv6 Island Network. At first, i build one (1) PC Router or one (1) network, i call it as Network A. All PC's or Laptop's (node's) that connect to Network A can communicated to each other (as usual, because it's in the same network). But then, I build one (1) other network, which is Network B. The problem occur when I want connect/communicate/ping PC's/Laptop's (nodes) in Network A to Network B, it's say that the 'Destination is unreachable:No route' or sometimes it say 'Network is unreachable' . I don't know why. I try to fix this problem.. but i really cannot. This is the coding that I made for PC router Network A :

hostname RouterA
password zebra
enable password zebra

interface eth0
bandwidth 100
ipv6 address 2407:4000:c::1/64
no ipv6 nd suppress-ra

interface eth1
bandwidth 100
ipv6 address 2407:4000:a::1/64
no ipv6 nd suppress-ra
ipv6 nd prefix 2407:4000:a::/64

interface lo

ipv6 route 2407:4000: b::/64 2407:4000:c::2

ipv6 forwarding

line vty

is anyone can help me? is there any mistake in my coding? how can i connect two network ipv6?

need help,

If the router is a Linux box, you have to enable packet forwarding via:

sysctl net.ipv6.conf.eth0.forwarding 1

Thank you for reply..really appreciate!vWhere should i type that code?

command line. Put it in /etc/sysctl.conf to make it permanent (uh, but the syntax will be like this: var = value)

Okay.. tq alot.. i will try it first.. if there is still error.. i will show it.. huhu
