Hi.

I try to configure de folloing scenary - Embedded RP with IPv6

I used 3 cisco 2600 routers:'Cisco IOS Software, C2600 Software (C2600-ADVENTERPRISEK9-M), Version 12.4(5), RELEASE SOFTWARE (fc3)'

For cliente and server streamnig, i used Videolan-Client

I have end-to-end conectivity - in R1 i can ping sucessefully 2001:ddd::1

In R2, i have configured de serial0/1 with: IPv6 address 2001:ccc:beef:feed::1/32

in the same router, R2, i configured: 'ipv6 pim rp-address 2001:CCC:BEEF:FEED::1'

all routers have enable embedded rp: 'IPv6 pim rp embedded'

but when i put VLC to stream at address [FF76:140:2001:CCC:beef:feed::1], the cisco IOS reboot...

What is a problem?? bug in IOS, bad configurations??

Hi

SegV exceptions are mostly turned as a S/W (IOS) related issue..

Also the notable possible reasons for the same are

1)Access to an invalid memory address

2)Write access to a read-only memory region

3)A jump to an invalid PC (often 0x0)

would also suggest to check this link if u havent seen this earlier..
