BGP 4-Byte ASN

[lxcollin1]

Hello,

Does the Cisco 7600 router support a 4-Byte BGP ASN? Are there any problems with using a 4-Byte ASN?

Thanks,

Lee

IOS XR supports 4-byte ASN since 3.4.

IOS will support 4-byte ASN;

12.2SRD for 7600 and 7200

12.5T for 1800/2800/3800, 7200, and 7300

12.2SB-Rel6 for 7200, 7300, 10000

12.2SX for 6500

I can confirm that 7600 IOS 12.2(33)SRD doesn't support the feature.
