Verifying iBGP

iBGP neighbors use the same messages and neighbor states as eBGP peers. As a result, the same commands in Chapter 13 for BGP neighbor verification can be used for iBGP peers. Example 14-3 shows a couple of examples, using Router E1’s iBGP neighbor relationship with E2 (10.100.1.2) based on the configuration in Example 14-2.
