[f-nsp] IPv6 on MLX

I am trying to get IPv6 configured on an MLX and it doesn't seem to to be
working.

I have two routers connected to each other with ipv6 configured on a ve
thusly:

First Router

ipv6 unicast-routing
interface ve 197
 port-name To SJC2
 ip rip v2-only
 ip address 216.52.87.245/30
 ipv6 address 2620:0:5100::/64 eui-64
 ipv6 enable

telnet at SJC-BGW-01#sho ipv6 interface ve 197
Interface VE 197 is up, line protocol is up
  vlan id: 197
  members: ethe 1/3 to 1/4
  active: ethe 1/3 to 1/4
  IPv6 is enabled, link-local address is fe80::21b:edff:feae:bc00
[Preferred]
  Global unicast address(es):
    2620:0:5100:0:21b:edff:feae:bc00 [Preferred],  subnet is
2620:0:5100::/64
    2620:0:5100:: [Anycast],  subnet is 2620:0:5100::/64

Second Router

ipv6 unicast-routing

interface ve 197
 ip rip v2-only
 ip address 216.52.87.246/30
 ipv6 address 2620:0:5150::/64 eui-64
 ipv6 enable

telnet at SJC-BGW-02#sho ipv6 interface ve 197
Interface VE 197 is up, line protocol is up
  vlan id: 197
  members: ethe 1/3 to 1/4
  active: ethe 1/4
  IPv6 is enabled, link-local address is fe80::21b:edff:feae:de00
[Preferred]
  Global unicast address(es):
    2620:0:5150:0:21b:edff:feae:de00 [Preferred],  subnet is
2620:0:5150::/64
    2620:0:5150:: [Anycast],  subnet is 2620:0:5150::/64

But I can not ping between them.

from the second router to the first:

telnet at SJC-BGW-02#ping ipv6 2620:0:5100:0:21b:edff:feae:bc00
Sending 1, 16-byte ICMPv6 Echo to 2620:0:5100:0:21b:edff:feae:bc00
timeout 5000 msec, Hop Limit 0
Type Control-c to abort
Request timed out.
No reply from remote host.

And sho ipv6 neigh shows only the link local IP, not the address I assigned:

telnet at SJC-BGW-02#sho ipv6 neigh
Total number of Neighbor entries: 1
    IPv6 Address                     VLAN  LinkLayer-Addr State Age Port
IsR
1   fe80::21b:edff:feae:bc00          197  001b.edae.bc00 STALE 1856ve
197    1

I am probably missing some very basic step someplace.  Can anyone toss me a
clue?
