knowing hello time can be done through interface but i had experimented with
a hold time value through debugging i dont know my interpretation is correct
but i thought of pasting it here
r1(config-if)#do debug ip packet detail dump
IP packet debugging is on (detailed) (dump)
*Mar 1 00:29:29.107: IP: s=2.2.2.2 (local), d=224.0.0.10 (Loopback2), len
60, sending broad/multicast, proto=88
07DCA3B0: 45C0003C 00000000 E@.<....
07DCA3C0: 0258D39C 02020202 E000000A 0205EEC2 .XS.....`.....nB
07DCA3D0: 00000000 00000000 00000000 0000000A ................
07DCA3E0: 0001000C 01000100 0000000F 00040008 ................
some of the results are
0258d39c -> 2 : 88 (i think this is the protocol) : 211(when compared with
others i think this is sequence number next was 212 and third was 213 and so
on) : 156
02020202 -> clearly our source ip 2.2.2.2
e000000a - > 224.0.0.10 mcast address
0205eec2 -> 2: 5( this is our hello time again iam not sure iam just seeing
the dump) : 238:194
0000000a -> this is our as number 10
0000000f -> 15 (this should be our hold time (again iam not sure just single
interpretation)
i will let you know if i find any
