Syntax
aggregate-address { ipv4-prefix mask | ipv6-prefix/prefix-length } [as-set]
[summary-only]
no aggregate-address { ipv4-prefix mask | ipv6-prefix/prefix-length } [as-set]
[summary-only]
• ipv4-prefix mask —A summary prefix and mask in dotted-quad notation.
The default route (0.0.0.0 0.0.0.0) cannot be configured as an aggregate-
address. The mask cannot be a 32-bit mask (255.255.255.255). The
combination of prefix and mask must be a valid IPv4 unicast destination
prefix
• ipv6-prefix —An IPv6 network prefix. This argument must be in the form
documented in RFC 2373 where the address is specified in hexadecimal
using 16-bit values between 0x00 and 0xff and separated by colons.
Counters are cleared only for the matching prefixes.
