arden on ipv6 tunnels with frame...

i love this guy...

http://ardenpackeer.com/tutorials/routeswitch/tutorial-ipv6-tunnels-part-1-manual-gre-ipv6ip-tunnels/

i expect at some point i will go through all the labs on his site... i like that he keeps things narrowly focused with his topologies so that the salient points can be illustrated...

with only 3 routers the frame switch is terribly easy to make...

1:102 goes to 2:201
1:103 goes to 3:301

the interfaces are thus:

r1

interface Loopback0
 ip address 10.10.10.10 255.255.255.255
!
interface FastEthernet0/0
 no ip address
 speed auto
 duplex auto
 ipv6 address 2001:1:1:1::1/64
!
interface Serial1/0
 ip address 10.1.123.1 255.255.255.0
 encapsulation frame-relay
 ip ospf network point-to-multipoint
 serial restart-delay 0
 frame-relay map ip 10.1.123.3 103 broadcast
 frame-relay map ip 10.1.123.2 102 broadcast
 no frame-relay inverse-arp

r2

interface Loopback0
 ip address 10.20.20.20 255.255.255.255
!
interface FastEthernet0/0
 no ip address
 speed auto
 duplex auto
 ipv6 address 2001:2:2:2::2/64

interface Serial1/0
 ip address 10.1.123.2 255.255.255.0
 encapsulation frame-relay
 ip ospf network point-to-multipoint
 serial restart-delay 0
 frame-relay map ip 10.1.123.3 201
 frame-relay map ip 10.1.123.1 201 broadcast
 no frame-relay inverse-arp

r3

interface Loopback0
 ip address 10.30.30.30 255.255.255.255
!
interface FastEthernet0/0
 no ip address
 speed auto
 duplex auto
 ipv6 address 2001:3:3:3::3/64

interface Serial1/0
 ip address 10.1.123.3 255.255.255.0
 encapsulation frame-relay
 ip ospf network point-to-multipoint
 serial restart-delay 0
 frame-relay map ip 10.1.123.2 301
 frame-relay map ip 10.1.123.1 301 broadcast
 no frame-relay inverse-arp

add the ospf networks for each router... arden seems to be fond of the zero's although i don't really like that... he also specifically states the router-id as the lo0's in the config... that'll happen anyway...

network 0.0.0.0 255.255.255.255 area 0

i always like to verify the frame map...

R1#sh frame map
Serial1/0 (up): ip 10.1.123.2 dlci 102(0x66,0x1860), static,
              broadcast,
              CISCO, status defined, active
Serial1/0 (up): ip 10.1.123.3 dlci 103(0x67,0x1870), static,
              broadcast,
              CISCO, status defined, active

R3#sh ip route

Gateway of last resort is not set

      10.0.0.0/8 is variably subnetted, 7 subnets, 2 masks
