Default Import and Export Policies for Protocols

Table 1: Default Import and Export Policies for Protocols

Importing or Exporting Protocol

Default Import Policy

Default Export Policy

BGP

Accept all BGP IPv4 routes learned from configured neighbors and import into the inet.0 routing table. Accept all BGP IPv6 routes learned from configured neighbors and import into the inet6.0 routing table.

Accept and export active BGP routes.

DVMRP

Accept all DVMRP routes and import into the inet.1 routing table.

Accept and export active DVMRP routes.

IS-IS

Accept all IS-IS routes and import into the inet.0 and inet6.0 routing tables. (You cannot override or change this default policy.)

Reject everything. (The protocol uses flooding to announce local routes and any learned routes.)

LDP

Accept all LDP routes and import into the inet.3 routing table.

Reject everything.

MPLS

Accept all MPLS routes and import into the inet.3 routing table.

Accept and export active MPLS routes.

OSPF

Accept all OSPF routes and import into the inet.0 routing table. (You cannot override or change this default policy.)

Reject everything. (The protocol uses flooding to announce local routes and any learned routes.)

PIM dense mode

Accept all PIM dense mode routes and import into the inet.1 routing table.

Accept active PIM dense mode routes.

PIM sparse mode

Accept all PIM sparse mode routes and import into the inet.1 routing table.

Accept and export active PIM sparse mode routes.

Pseudoprotocol:

  • Direct routes
  • Explicitly configured routes:
    • Aggregate routes
    • Generated routes
    • Static routes

Accept all direct and explicitly configured routes and import into the inet.0 routing table.

The pseudoprotocol cannot export any routes from the routing table because it is not a routing protocol.

Routing protocols can export these or any routes from the routing table.

RIP

Accept all RIP routes learned from configured neighbors and import into the inet.0 routing table.

Reject everything. To export RIP routes, you must configure an export policy for RIP.

RIPng

Accept all RIPng routes learned from configured neighbors and import into the inet6.0 routing table.

Reject everything. To export RIPng routes, you must configure an export policy for RIPng.

Test policy

Accept all routes. For additional information about test policy, see Routing Policy Tests.
