OSPFv3 and ipsec

Tomas Fidler

Hello,

I experiment with OSPFv3 and encryption but without success.

My configuration is 2x2901 with c2900-universalk9-mz.SPA.150-1.M4.bin (security and data licence) crossconnected thru s0/0/0 (tried HDLC and PPP)

ospfv3 works well, but when I try to enable encryption neighborship goes down and router says:

*Feb 24 10:20:43.239: IPV6: source FE80::E25F:B9FF:FECC:FE88 (local)
*Feb 24 10:20:43.239:       dest FF02::5 (Serial0/0/0)
*Feb 24 10:20:43.239:       traffic class 224, flow 0x0, len 76+0, prot 89, hops 1, originating
*Feb 24 10:20:43.239: IPv6-Fwd: Packet consumed by from_us feature 'IPsec protection for locally-generated IPv6 pak'

so no hello packets are forwarded.

I use simple ospf configuration and this command on both routers:

      ipv6 ospf encryption ipsec spi 300 esp des 1234567890123456 md5 12345678901234567890123456789012

Any help appreciated.

Tomas

PS: if it works with other 15's image please let me know.
