map add domain

Summary/usage

map add domain ip4-pfx <ip4-pfx> ip6-pfx <ip6-pfx> ip6-src <ip6-pfx> ea-bits-len <n> psid-offset <n> psid-len <n> [map-t] [mtu <mtu>].

Description

Add MAP domain

Example usage
vpp# map add domain

Declaration and implementation

Declaration: map_add_domain_command (src/vnet/map/map.c line 2124)

Implementation: map_add_domain_command_fn.

map add rule

Summary/usage

map add rule index <domain> psid <psid> ip6-dst <ip6-addr>.

Description

Add MAP rule to a domain

Example usage
vpp# map add rule

Declaration and implementation

Declaration: map_add_rule_command (src/vnet/map/map.c line 2139)

Implementation: map_add_rule_command_fn.

map del domain

Summary/usage

map del domain index <domain>.

Description

Delete MAP domain

Example usage
vpp# map del domain

Declaration and implementation

Declaration: map_del_command (src/vnet/map/map.c line 2152)

Implementation: map_del_domain_command_fn.

map params fragment

Summary/usage

map params fragment inner|outer.

Description

Configure MAP fragmentation behaviour

Example usage
vpp# map params fragment

Declaration and implementation

Declaration: map_fragment_command (src/vnet/map/map.c line 2074)

Implementation: map_fragment_command_fn.

map params fragment ignore-df

Summary/usage

map params fragment ignore-df on|off.

Description

Ignore the IPv4 Don't fragment bit

Example usage
vpp# map params fragment ignore-df

Allows fragmentation of the IPv4 packet even if the DF bit is set. The choice between inner or outer fragmentation of tunnel packets is complicated. The benefit of inner fragmentation is that the ultimate endpoint must reassemble, instead of the tunnel endpoint.

Declaration and implementation

Declaration: map_fragment_df_command (src/vnet/map/map.c line 2093)

Implementation: map_fragment_df_command_fn.

map params icmp source-address

Summary/usage

map params icmp source-address <ip4-address>.

Description

Specifiy the IPv4 source address used for relayed ICMP error messages

Example usage
vpp# map params icmp source-address
This command specifies which IPv4 source address (must be local to the system), that is used for relayed received IPv6 ICMP error messages.

Declaration and implementation

Declaration: map_icmp_relay_source_address_command (src/vnet/map/map.c line 2045)

Implementation: map_icmp_relay_source_address_command_fn.

map params icmp6 unreachables

Summary/usage

map params icmp6 unreachables {on|off}.

Description

Send IPv6 ICMP unreachables

Example usage
vpp# map params icmp6 unreachables
Send IPv6 ICMP unreachable messages back if security check fails or no MAP domain exists.

Declaration and implementation

Declaration: map_icmp_unreachables_command (src/vnet/map/map.c line 2061)

Implementation: map_icmp_unreachables_command_fn.

map params pre-resolve

Summary/usage

 map params pre-resolve {ip4-nh <address>} | {ip6-nh <address>}.

Description

Bypass IP4/IP6 lookup

Example usage
vpp# map params pre-resolve
Bypass a second FIB lookup of the translated or encapsulated packet, and forward the packet directly to the specified next-hop. This optimization trades forwarding flexibility for performance.

Declaration and implementation

Declaration: map_pre_resolve_command (src/vnet/map/map.c line 2010)

Implementation: map_pre_resolve_command_fn.

map params reassembly

Summary/usage

map params reassembly [ip4 | ip6] [lifetime <lifetime-ms>] [pool-size <pool-size>] [buffers <buffers>] [ht-ratio <ht-ratio>].

Description

Configure MAP reassembly behaviour

Example usage
vpp# map params reassembly

Declaration and implementation

Declaration: map_ip4_reass_lifetime_command (src/vnet/map/map.c line 1972)

Implementation: map_params_reass_command_fn.

map params security-check

Summary/usage

map params security-check on|off.

Description

Enable or disable the MAP-E inbound security check

Example usage
vpp# map params security-check
By default, a decapsulated packet's IPv4 source address will be verified against the outer header's IPv6 source address. Disabling this feature will allow IPv4 source address spoofing.

Declaration and implementation

Declaration: map_security_check_command (src/vnet/map/map.c line 2028)

Implementation: map_security_check_command_fn.

map params security-check fragments

Summary/usage

map params security-check fragments on|off.

Description

Specifiy if the inbound security check should be done on fragments

Example usage
vpp# map params security-check fragments
Typically the inbound on-decapsulation security check is only done on the first packet. The packet that contains the L4 information. While a security check on every fragment is possible, it has a cost. State must be created on the first fragment.

Declaration and implementation

Declaration: map_security_check_frag_command (src/vnet/map/map.c line 2111)

Implementation: map_security_check_frag_command_fn.

map params traffic-class

Summary/usage

map params traffic-class {0x0-0xff | copy}.

Description

Set or copy the IP TOS/Traffic Class field

Example usage
vpp# map params traffic-class
This command is used to set the traffic-class field in translated or encapsulated packets. If copy is specifed (the default) then the traffic-class/TOS field is copied from the original packet to the translated / encapsulating header.

Declaration and implementation

Declaration: map_traffic_class_command (src/vnet/map/map.c line 1992)

Implementation: map_traffic_class_command_fn.

show map domain

Summary/usage

show map domain index <n> [counters].

Description

Declaration and implementation

Declaration: show_map_fragments_command (src/vnet/map/map.c line 2191)

Implementation: show_map_fragments_command_fn.

show map stats

Summary/usage

Description

Show MAP statistics

Example usage
vpp# show map stats

Declaration and implementation

Declaration: show_map_stats_command (src/vnet/map/map.c line 2178)

Implementation: show_map_stats_command_fn.
