Hello

I have been unable to resolve my problem to date.

>From RFC3775, Section 15.4.5: "If a correspondent node finds that it is
spending more resources on checking bogus Binding Updates than it is
likely to save by accepting genuine Binding Updates, then it may
silently discard some or all Binding Updates without performing any
cryptographic operations."

I assume that it is for this (or another similar) reason that the HA
rejects the BU and I get a "status 130" (insufficient resources)
message. However, I am at a loss about to how to get around this
problem.

I would really appreciate any useful suggestions.

Thank you.

Regards
Madhush

Subject: BU error

Hi all

I have a MIPL test-bed and the IPv6 network seems to be working fine. My
test-bed configuration is as follows:

Home subnet prefix- 2001:5c0:8d03:1::/64
Foreign subnet prefix- 2001:5c0:8d03:2::/64
Home Agent address- 2001:5c0:8d03:1::1/64
Mobile Node: Home address- 2001:5c0:8d03:1::99/64, 
                 Care-of address- 2001:5c0:8d03:2:211:20ff:fe48:246/64

When my MN moves to the foreign subnet and sends a BU to the HA, I get
an error: The HA receives the BU and creates a tunnel, then seems to
delete it immediately. The Binding Acknowledge status code 130 is
"insufficient resources" according to the RFC. The output I get at the
HA is pasted below:

I'm not sure what to make of this or how to resolve the problem. Can
anyone help?

Thank you.
