7. The router boots.

8. The router uses TFTP to get application ﬁles as it needs them.

The ASN can continue to request ﬁles, even after it begins bridging and

routing trafﬁc.

9. The router begins bridging and routing network trafﬁc in accordance with the

conﬁguration ﬁle.

If a network boot fails, the ASN waits to be booted by a neighboring slot. (A

single-slot ASN will instead attempt the Local Boot procedure.)

Note: The ASN supports Netbooting over multiple slots. The ﬁrst slot to

retrieve startup ﬁles forces the other slots to use those ﬁles.
