BigIron RX Series Configuration Guide 109353-1001810-01Clearing global IPv6 information 43You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values between colonsas documented in RFC 2373. You must specify the <prefix-length> parameter as a decimal value. Aslash mark (/) must follow the <ipv6-prefix> parameter and precede the <prefix-length>parameter.You must specify the <ipv6-address> parameter in hexadecimal using 16-bit values betweencolons as documented in RFC 2373.The ethernet | tunnel | ve parameter specifies the interfaces for which you can remove cacheentries. If you specify an Ethernet interface, also specify the port number associated with theinterface. If you specify a VE or tunnel interface, also specify the VE or tunnel number, respectively.Clearing IPv6 neighbor informationYou can remove all entries from the IPv6 neighbor table or specify an entry based on the following:• IPv6 prefix.• IPv6 address.• Interface type.For example, to remove entries for Ethernet interface 3/1, enter the following command at thePrivileged EXEC level or any of the CONFIG levels of the CLI.BigIron RX# clear ipv6 neighbor ethernet 3/1Syntax: clear ipv6 neighbor [<ipv6-prefix>/<prefix-length> | <ipv6-address> | ethernet <port> |ve <number>]You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values between colonsas documented in RFC 2373. You must specify the <prefix-length> parameter as a decimal value. Aslash mark (/) must follow the <ipv6-prefix> parameter and precede the <prefix-length>parameter.You must specify the > parameter in hexadecimal using 16-bit values betweencolons as documented in RFC 2373.The ethernet | ve parameter specifies the interfaces for which you can remove cache entries. If youspecify an Ethernet interface, also specify the port number associated with the interface. If youspecify a VE, also specify the VE number.Clearing IPv6 routes from the IPv6 route tableYou can clear all IPv6 routes or only those routes associated with a particular IPv6 prefix from theIPv6 route table and reset the routes.For example, to clear IPv6 routes associated with the prefix 2000:7838::/32, enter the followingcommand at the Privileged EXEC level or any of the Config levels of the CLI.BigIron RX# clear ipv6 route 2000:7838::/32Syntax: clear ipv6 route [<ipv6-prefix>/<prefix-length>]The <ipv6-prefix>/<prefix-length> parameter clears routes associated with a particular IPv6 prefix.You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values between colonsas documented in RFC 2373. You must specify the <prefix-length> parameter as a decimal value. Aslash mark (/) must follow the <ipv6-prefix> parameter and precede the <prefix-length>parameter.
