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:
| 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. | |
