[Cisco] IPv6 router configuration - Help needed

post #1 of 6
Thread Starter 
Here is the deal. I'm working with 6 2500 series routers. we have the proper IOS installed however we have hit a wall working with IPv6. The goal is to configure the routers each with ipv6 make them talk to each other and to do routing. We are also needing to use BGP. We have 2 serial ports on each router. Its a closed network. in other words no internet.

What i am looking for is a basic setup to get these interfaces up and pinging each other. I do not mind if you tell me what commands to do but if you can go a step father and explain a little bit that would be very appreciated.

example

>enable
# conf t
(config) interface s1
.... ipv6 enable
..... ipv6 address XXXX::1/XX



that kinda of stuff. please assume that i have 0 knowledge (keep the jokes to yourself ) so dont assume that i have ipv6 unicast set and things like that.

Thanks in advance for any help received. My dead line to get these routers talking to each other is thursday the 4th.

Little background on whats going on. this is an extra credit project for my CCNA class there is a group of us working on it my teacher felt it would be cool to throw a little ccnp type stuff at us hence the bgp as well. Our basic goal is again ipv6 talking and routing with bgp pretty much thats it. The teacher said we can use any and whatever resources we have available to us except for him. so forum asking is fair game and this is one of the best places i know to ask.

SUMMARY STEPS

1.enable
2.configure terminal
3.interface type number
4.ipv6 addressipv6-prefix/prefix-length eui-64
or
ipv6 address ipv6-address/prefix-length link-local
or
ipv6 addressipv6-prefix/prefix-length anycast
or
ipv6 enable
5.exit
6.ipv6 unicast-routing
DETAILED STEPS


Command or Action
Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
interface type number
Example:
Router(config)# interface ethernet 0/0
Specifies an interface type and number, and places the router in interface configuration mode.
Step 4
ipv6 address ipv6-prefix/prefix-length eui-64
or
ipv6 address ipv6-address/prefix-length link-local


or
ipv6 address ipv6-prefix/prefix-length anycast
or
ipv6 enable
Example:
Router(config-if)# ipv6 address 2001B8:0:1::/64 eui-64


or
Example:
Router(config-if)# ipv6 address FE80::260:3EFF:FE11:6770 link-local


or
Example:
Router(config-if) ipv6 address 2001B8:1:1:FFFF:FFFF:FFFF:FFFE/64 anycast


or
Example:
Router(config-if)# ipv6 enable
Specifies an IPv6 network assigned to the interface and enables IPv6 processing on the interface.
or
Specifies an IPv6 address assigned to the interface and enables IPv6 processing on the interface.
or
Automatically configures an IPv6 link-local address on the interface while also enabling the interface for IPv6 processing. The link-local address can be used only to communicate with nodes on the same link.
Specifying the ipv6 address eui-64 command configures global IPv6 addresses with an interface identifier (ID) in the low-order 64 bits of the IPv6 address. Only the 64-bit network prefix for the address needs to be specified; the last 64 bits are automatically computed from the interface ID.
Specifying the ipv6 address link-local command configures a link-local address on the interface that is used instead of the link-local address that is automatically configured when IPv6 is enabled on the interface.
Specifying the ipv6 address anycast command adds an IPv6 anycast address.
Step 5
exit
Example:
Router(config-if)# exit
Exits interface configuration mode, and returns the router to global configuration mode.
Step 6
ipv6 unicast-routing
Example:
Router(config)# ipv6 unicast-routing
Enables the forwarding of IPv6 unicast datagrams.


I think this might be what i was looking for. Theres a ton of info in that link you provided. Thanks

Well its always a ton of info, it's Cisco's website
Everything Cisco is documented on their website, just not in a teacher-student type of fashion, it has an extremely harsh learning curve and lacks any sort of educational structure but you can still learn from it. As in its knowledge, but there is no one there to guide you through the Labyrinth that is Cisco's Knowledge base.
If you ever doubt something you read about in learning material that is not from Cisco officially, they always have their insanely large knowledge base to confirm/deny any statements.

Honestly, I would maybe learn about routing with EIGRP for IPv6, RIPng, and OSPFv3 before BGP. BGP in itself is a big concept to learn on its own. Its an Exterior routing protocol, so it can become pretty complex. Best way to go is get the concept down first then start practicing it.

Also, since you seem to be getting into Cisco:
www.networking-forum.com are where a lot of Cisco gurus are. (I use it myself) They're reluctant to downright answer homework questions because they would rather you learn the whys and hows of something, but none the less I have seen some insanely complex things get worked out there. This is OCN's networking section of the forums, but this forum is entirely dedicated to networking.

Thanks. I didn't pick the routing protocol. Ive heard BGP is a ***** too but its a challenge and i stepped up to work on the project. thanks again for the info. Ive looked through ciscos knowledge base before. just didn't dig in the right section i guess.
