[c-nsp] IOS and 4 byte ASNs

[Lars Lystrup Christensen]

Hi Dmitry

Well... It depends on whether you have been given a 4-byte ASN or it is
your neighbor, who has the 4-byte ASN.

Have a look at
http://as4.cluepon.net/index.php/Example_Configurations#Cisco_IOS

To be honest, I haven't done any setups yet with the 4-byte ASN, but it
may be interesting to do some testing...

Regards,

Does its mean that I should configure "router bgp 23456" if already have
32-bit ASN?
And what I should do if my eBGP neighbor have 32-bit ASN too and run
this fine
software called "IOS"?
 router bgp 23456
  neighbor X.X.X.X remote-as 23456
  neighbor X.X.X.X allowas-in
?
