RIP sends Updates with TTL of 2

From my past studies I always thought that Routing Protocol updates are of Link Local scope in nature and have a TTL value of 1 without caring about that it will be using some multicast address or broadcast address for sending this out.

But things got changed when some friend from Cisco TAC told me that the TTL value for RIP update packet is 2, And I was like...........ahhh MAN...Is it ?

So finally I decided to lab this up by using GNS. I captured some RIP update packets using GNS capture feature and's true...however this can not be seen in #debug ip rip output

Just take a look at the packet  :)

CCIE#XXXXX....Oops that number is still missing ;)
