Ok, stupid question I know, but I want to be 100% sure before I commit to anything...
1. If I'm going to Dual home ISPs, I will NEED to have an ASN correct?
2. On my router, if I do router bgp ? I get the following options: Router(config)#router bgp ?
<1-65535> Autonomous system number
<1.0-XX.YY> 4 Octets Autonomous system number
Does this mean this router supports a 4-byte ASN? What does <1.0-XX.YY> mean? Are the 4-byte ASNs entered in a different format? Thanks!
