Hello list,

I tried to set up an ospf connection between one access Cisco router (CE) and Redback routers (PE) in lab. But the It stucks in Exchange state. 

Debug messages shows  EXCHANGE - OPTIONS/INIT not match

The Pcap shows DBD bits mismatch.  Any idea to change I and MS bis in Cisco router 1841.

.... .0.. = I: Init bit is NOT set
.... ..1. = M: More bit is SET
.... ...0 = MS: Master/Slave bit is NOT set

Redback

.... .1.. = I: Init bit is SET
