Parameters Examples Error messages |
The Remove TCP/IP Route (RMVTCPRTE) command removes a previously identified route from the Transmission Control Protocol/Internet Protocol (TCP/IP) configuration.
Five parameter values uniquely define an IPv4 route. These values are the route destination (RTEDEST), the subnet mask (SUBNETMASK), the type of service (TOS), the IPv4 address of the next system on the route (NEXTHOP), and the preferred binding interface (BINDIFC). For default routes and default multicast routes (*DFTROUTE and *DFTMCAST), the NEXTHOP, TOS and BINDIFC values uniquely define the route because the SUBNETMASK is always *NONE.
Four parameter values uniquely define an IPv6 route. These values are the route destination (RTEDEST), the address prefix length (ADRPFXLEN), the IPv6 address of the next system on the route (NEXTHOP), and the binding line description (BINDLIND).
Note: When a RMVTCPRTE command is entered using option 4 of the Work with TCP/IP Routes display, a confirmation display is shown. This display warns that the removal of a route might affect active TCP connections and that unpredictable results might occur. A confirmation display is not shown when the RMVTCPRTE CL command is issued directly.

Specifies the route destination being removed.
For an IPv4 route, you must specify all 4 bytes that make up an internet address though some of the bytes may be equal to 0. For example, a route to all the hosts on the 9.5.11 subnetwork is identified by entering 9.5.11.0 for the route destination. Used in combination with a subnetmask, type of service value, and next hop, the route destination uniquely identifies a route to a network or system.
For an IPv6 route, the entire 16 byte IPv6 address must be specified, and the suffix portion of the RTEDEST field must be zero. For example, a RTEDEST with value 1234:5678:: and address prefix length (ADRPFXLEN) of 32 is a valid combination, but a RTEDEST with value 1234:5678:8000:: and ADRPFXLEN of 32 is not.
This is a required parameter.
Note: When RTEDEST(*DFTMCAST) is specified, then SUBNETMASK(*NONE) must also be specified and the NEXTHOP parameter must be a local TCP/IP interface (on this system).
Any combination thereof means that you may specify a route, such as 9.5.0.0 to the hosts on the 9.5 subnet, even though all 9.5.x.x addresses are class A network addresses.
Exceptions:
For an IPv6 route, the route destination is specified in the form x:x:x:x:x:x:x:x, where x is a hexadecimal number ranging from 0 through X'FFFF'. "::" may be used once in the route destination to indicate one or more groups of 16 bits of zeros. The "::" may be used to compress leading, imbeddeded, or trailing zeros in the route destination. The suffix portion of the route destination must contain zeros.
| Top |
Specifies a bit mask that identifies to TCP/IP which bits of the value specified for the route destination (RTEDEST) compose the network and subnet portions of the internet address. By defining the network portion and subnetwork portion of the RTEDEST address, the subnet mask also defines which bits of the RTEDEST address make up the host portion.
The mask is a 32-bit combination that is logically ANDed with the internet address to determine a particular subnetwork. The bits of the mask set to the value one (1) determine the network and subnetwork portions of the address. The bits set to the value zero (0) determine the host portion of the address.
SUBNETMASK is ignored if RTEDEST contains an IPv6 address.
| Top |
Specifies the type of service to be used. The type of service defines how the internet hosts and routers should make trade-offs between throughput, delay, reliability, and cost.
TOS is ignored if RTEDEST contains an IPv6 address.
| Top |
Specifies the internet address of the next system (gateway) on the route.
Note: If RTEDEST specifies an IPv4 address, NEXTHOP must contain an IPv4 address. If RTEDEST specifies an IPv6 address, NEXTHOP must contain an IPv6 address.
An IPv4 internet address is specified in the form nnn.nnn.nnn.nnn, where nnn is a decimal number ranging from 0 through 255. An IPv4 internet address is not valid if it has a value of all binary ones or all binary zeros for the network identifier (ID) portion or the host ID portion of the address.
An IPv6 internet address is specified in the form x:x:x:x:x:x:x:x, where x is a hexadecimal number ranging from 0 through X'FFFF'. "::" may be used once in the IPv6 address to indicate one or more groups of 16 bits of zeros. The "::" may be used to compress leading, imbedded, or trailing zeros in the address.
:: (null IPv6 address), ::1 (IPv6 loopback address) and addresses beginning with FF (IPv6 multicast address) are not allowed.
If the internet address is entered from a command line, the address must be enclosed in apostrophes.
| Top |
Specifies the IPv6 address prefix length (in bits) of the RTEDEST parameter. The address prefix length specifies how much of the leftmost portion of an IPv6 address is the subnet prefix. This parameter applies only if RTEDEST is an IPv6 address.
| Top |
Specifies the IP interface this route is bound to.
BINDIFC is ignored if RTEDEST contains an IPv6 address.
| Top |
Specifies the line description (LIND) object to which this route is bound. This value must be specified for an IPv6 route and is ignored for an IPv4 route.

Example 1: Removing a Route
RMVTCPRTE RTEDEST('132.65.0.0') SUBNETMASK('255.65.0.0')
TOS(*MINDELAY) NEXTHOP('9.5.15.1')
This command removes the route identified as 132.65.0.0 with a subnetmask of 255.65.0.0, a type of service of *MINDELAY, and a next hop of 9.5.15.1.
Example 2: Removing a Default Route
RMVTCPRTE RTEDEST(*DFTROUTE) SUBNETMASK(*NONE)
NEXTHOP('186.34.76.92')
This command removes a host route identified as a default route (*DFTROUTE). The subnetmask is specified as *NONE and the type of service defaults to *NORMAL. The subnetmask, type of service, and next-hop value differentiate this *DFTROUTE from the other possible eight *DFTROUTE entries.
Example 3: Removing an IPv6 Route
RMVTCPRTE RTEDEST('1234:5678::') ADRPFXLEN(32)
NEXTHOP('AAAA::BBBB') BINDLIND(ETHLINE)
This command removes the IPv6 route identified with route destination 1234:5678::, address prefix length 32, next hop aaaa::bbbb, and binding line description ETHLINE.
Example 4: Removing an IPv6 Default Route
RMVTCPRTE RTEDEST(*DFT6ROUTE) ADRPFXLEN(*NONE)
NEXTHOP('AAAA::CCCC') BINDLIND(ETHLINE2)
This command removes the IPv6 default route identified with next hop aaaa::cccc, and binding line description ETHLINE2.
