redistribute { source-protocol } [ metric num | metric-type { type1 | type2 } | route-map string ]

redistribute { source-protocol } [ level-1 | level-1-2 | level-2 | metric num | metric-type { type1 | type2 } | route-map string ]

no redistribute isis [ level-1 | level-1-2 | level-2 metric num | route-map string ]

no redistribute isis { level-1 into level-2 } [ prefix-list name ]

no redistribute isis { level-2 into level-1 } [ prefix-list name ]

no redistribute ospf [ match { external1 | external2 | internal } | metric num | metric-type { type1 | type2 } | route-map string ]

no redistribute { source-protocol } [ metric num | metric-type { type1 | type2 } | route-map string ]

Command Default

The device does not redistribute routing information.

Parameters

isis

Specifies the IS-IS protocol.

level-1

Specifies L1 LSP, L1 CSNP, and LI PSNP packets.

level-1-2

Specifies L1 LSP, L1 CSNP, and LI PSNP packets and L2 LSP, L2 CSNP, and L2 PSNP packets.

level-2

Specifies L2 LSP, L2 CSNP, and L2 PSNP packets.

metric num

Specifies a metric for redistributed routes. Valid values range from 1 through 65535 in OSPFv2 and OSPFv3 configuration mode. Valid values range from 1 through 4261412863 in ISIS address-family IPv4/IPv6 unicast configuration mode and BGP address-family IPv4/IPv6 unicast configuration mode.

route-map string

Specifies a route map to be consulted before a route is added to the routing table.

level-1 into level-2

Redistributes Level 1 routes into Level 2.

level-2 into level-1

Redistributes Level 2 routes into Level 1.

prefix-list name

Specifies a prefix-list.

ospf

Specifies the OSPF protocol.

match

Specifies the type of route.

external1: Specifies OSPF Type 1 external routes.
external2: Specifies OSPF Type 2 external routes.
internal: Specifies OSPF internal routes.

metric-type

Specifies the external link type associated with the default route advertised into the OSPF routing domain.

type1: Specifies a type 1 external route.
type2: Specifies a type 2 external route.

source-protocol

Specifies the source protocol from which routes are being redistributed. It can be one of the following keywords: bgp, connected, or static.

Modes

BGP address-family IPv4 unicast configuration mode

BGP address-family IPv6 unicast configuration mode

BGP address-family IPv4 unicast VRF configuration mode

BGP address-family IPv6 unicast VRF configuration mode

ISIS address-family IPv4 unicast configuration mode

ISIS address-family IPv6 unicast configuration mode

OSPF router configuration mode

OSPFv3 router configuration mode

OSPF router VRF configuration mode

OSPFv3 router VRF configuration mode

Usage Guidelines

IS-IS is supported on devices based on the DNX chipset family. For a list of such devices, see "Supported Hardware".

Routes can be filtered by means of an associated route map before they are distributed.

The metric-type { type1 | type2 } option is only available in OSPFv3 router, OSPFv3 router VRF, and ISIS address-family /IPv4/IPv6 unicast configuration mode.

The redistribute { source-protocol } [ level-1 | level-1-2 | level-2 ] option is only available in ISIS address-family IPv4/IPv6 unicast configuration mode.

The match, metric, and metric-type options are not available in OSPF VRF configuration mode.

Note

The default-metric command does not apply to the redistribution of directly connected routes. Use a route map to change the default metric for directly connected routes.

The no form of the command restores the defaults.

Examples

The following example redistributes IS-IS routes, specifying level 1 packets, in BGP address-family IPv4 unicast configuration mode.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 unicast
device(config-bgp-ipv4u)# redistribute isis level-1

The following example redistributes all IPv4 IS-IS routes from Level 2 into Level 1.

device# configure terminal
device(config)# router isis
device(config-bgp-isis)# address-family ipv4 unicast
evice(config-bgp-ipv4u)# redistribute isis level-2 into level-1

The following example redistributes OSPF external type 1 routes with a metric of 200 in BGP address-family IPv4 unicast configuration mode.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 unicast
device(config-bgp-ipv4u)# redistribute ospf match external1 metric 200

The following example redistributes OSPFv3 external type 2 routes in BGP address-family IPv6 unicast configuration mode.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# redistribute ospf match external2

The following example redistributes static routes into BGP4 and specifies a metric of 200.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 unicast
device(config-bgp-ipv4u)# redistribute static metric 200

The following example redistributes directly connected routes into BGP4+.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# redistribute connected

The following example redistributes directly connected routes into IS-IS.

device# configure terminal
device(config)# router bgp
device(config-isis-router)# address-family ipv6 unicast 
device(config-router-isis-ipv6u)# redistribute connected

The following example redistributes BGP routes and specifies that route-map "rm7" be consulted in OSPF VRF configuration mode.

device# configure terminal
device(config)# router ospf
device(config-router-ospf-vrf-default-vrf)# redistribute bgp route-map rm7

The following example redistributes OSPF routes and specifies a type1 external route in OSPFv3 VRF configuration mode.

device# configure terminal
device(config)# ipv6 router ospf
device(config-ipv6-router-ospf-vrf-default-vrf)# redistribute ospf metric-type type1
