Hi,
We're looking to deploy IPv6 across our DSL subscriber base, we are almost there with the configuration but are having issues with 'first hop routing'.
An Example traceroute:
AlexMacBook:~ alexfossa$ traceroute6 www.he.net
traceroute6 to he.net (2001:470:0:76::2) from 2a00:1990:1:1:226:bbff:fe03:c6a7, 64 hops max, 12 byte packets
1 2a00:1990:1:1::1 1.886 ms 1.729 ms 1.344 ms
2 * * *
3 xe-2-3-0-103.lon14.ip6.tinet.net 17.873 ms 15.415 ms 15.625 ms
4 xe-1-1-0.lon10.ip6.tinet.net 15.301 ms 15.124 ms 16.474 ms
5 10gigabitethernet1-1.core1.lon1.he.net 20.605 ms 23.679 ms 24.902 ms
6 10gigabitethernet2-3.core1.ny4.ipv6.he.net 83.626 ms 93.947 ms
10gigabitethernet4-4.core1.nyc4.he.net 83.690 ms
7 10gigabitethernet5-3.core1.lax1.he.net 150.774 ms 147.256 ms 156.679 ms
8 10gigabitethernet1-3.core1.pao1.ipv6.he.net 159.380 ms 152.882 ms 152.470 ms
9 10gigabitethernet1-2.core1.fmt1.ipv6.he.net 155.702 ms 155.004 ms 168.266 ms
1st hop is my Cisco ADSL router here, 2nd should be the Loopback interface referenced to in the Virtual-template.
Here is my Virtual-Template and Loopback config:
interface Virtual-Template3
mtu 1502
ip unnumbered Loopback3
ip mtu 1500
ip tcp adjust-mss 1450
no logging event link-status
ipv6 enable
ipv6 verify unicast reverse-path
ipv6 ospf 1 area 0
no snmp trap link-status
no peer default ip address
ppp max-failure 1
ppp mtu adaptive
ppp authentication chap
ppp ipcp address required
ppp link reorders
ppp multilink
ppp multilink fragment disable
ppp multilink endpoint hostname
interface Loopback3
ip address 77.246.20.33 255.255.255.255
ipv6 address 2A00:1990:FEED:1::1/128
ipv6 enable
ipv6 ospf 1 area 0
end
Any help gratefully received.
Many Thanks,
Alex
