Crypto Across two catalyst 6509s

Hello,

I noticed something strange recently. I don't know if anybody can help me
with an explanation. the connection between the two catalyst 6509 switches
are routed and I have a number of SVIs on both switches (the SVIs serves as
gateway for a number of vlans). i have a GRE over IPSEC tunnel across the
routed interfaces of the catalyst switches. Everything works fine if traffic
is passing over the routed interfaces and not the tunnels. However, if I
force the traffic to pass across the tunnel, the SVIs become unreachable
from both sides but the end devices are reachable. A show command confirms
that the traffic is being encrypted.

Regards,

Mayokun.
