TCP/IP profile record Routing section

This section provides configured routing information from the BEGINROUTES statement block and the GATEWAY statement. There can be multiple sections in the record, one per ROUTE substatement or GATEWAY route entry.

Table 1 shows the TCP/IP profile record routing section.

Table 1. TCP/IP profile record routing section
Offset	Name	Length	Format	Description
0(X'0')	NMTP_ROUTEEye	4	EBCDIC	ROUT eyecatcher
4(X'4')	NMTP_ROUTFlags	2	Binary	Flags: X'8000', NMTP_ROUTIPv6: IPv6 indicator. If set, this is an IPv6 route. X'4000', NMTP_ROUTDefault: If set, this is a default route so there is no destination IP address. X'2000', NMTP_ROUTNextHop: If set, a next hop address was specified. X'1000', NMTP_ROUTDelayAcks: If set, DELAYACKS was specified. X'0800', NMTP_ROUTReplaceable: If set, REPLACEABLE was specified. X'0400', NMTP_ROUTReplaced: If set, this is a replaceable static route which has been replaced by a dynamic route. This route is not currently being used by the TCP/IP stack.
6(X'6')	NMTP_ROUTMtu	2	Binary	MTU size
8(X'8')	NMTP_ROUTDestPfxLen	1	Binary	Destination prefix length for both IPv4 or IPv6 destination addresses. This value is set to the maximum IPv4 (32) or IPv6(128) value in the following cases: If the HOST parameter was specified as the IPv4 address mask or IPv6 prefix length. A prefix length was not specified.
9(X'9')		3	Binary	Reserved
12(X'C')	NMTP_ROUTIfIndex	4	Binary	Interface index of interface over which route is defined.
16(X'10')	NMTP_ROUTMaxRetranTime	4	Binary	Maximum retransmission time in milliseconds.
20(X'14')	NMTP_ROUTMinRetranTime	4	Binary	Minimum retransmission time in milliseconds.
24(X'18')	NMTP_ROUTRoundTripGain	2	Binary	Round trip gain percentage in thousandths of seconds.
26(X'1A')	NMTP_ROUTVarGain	2	Binary	Variance gain percentage in thousandths of seconds.
28(X'1C')	NMTP_ROUTVarMultiplier	4	Binary	Variance multiplier value in thousandths if seconds.
32(X'20')	NMTP_ROUTIntfName	16	EBCDIC	Name of interface over which route is defined, padded with trailing blanks.
48(X'30')	NMTP_ROUTDestAddr4	4	Binary	One of the following values: If the NMTP_ROUTIPv6 flag is not set, this field contains the IPv4 destination IP address. If the NMTP_ROUTIPv6 flag is set, this field contains the IPv6 destination IP address.
48(X'30')	NMTP_ROUTDestAddr6	16	Binary	One of the following values: If the NMTP_ROUTIPv6 flag is not set, this field contains the IPv4 destination IP address. If the NMTP_ROUTIPv6 flag is set, this field contains the IPv6 destination IP address.
64(X'40')	NMTP_ROUTNextHopAddr4	4	Binary	Next hop IP address. This field is only valid if flag NMTP_ROUTNextHop is set. The value is one of the following: If the NMTP_ROUTIPv6 flag is not set, this field contains the IPv4 next hop IP address. If the NMTP_ROUTIPv6 flag is set, this field contains the IPv6 next hop IP address.
64(X'40')	NMTP_ROUTNextHopAddr6	16	Binary	Next hop IP address. This field is only valid if flag NMTP_ROUTNextHop is set. The value is one of the following: If the NMTP_ROUTIPv6 flag is not set, this field contains the IPv4 next hop IP address. If the NMTP_ROUTIPv6 flag is set, this field contains the IPv6 next hop IP address.
