Step Command Remarks The defaults are as follows: 4. (Optional.) Configure the type codes of OSPF extended community attributes. ext-community-type { domain-id type-code1 | router-id type-code2 | route-type type-code3 } • 0x0005 for Domain ID. • 0x0107 for Router ID. • 0x0306 for Route Type. 5. (Optional.) Configure the external route tag for imported VPN routes. route-tag tag-value By default, no route tag is configured. In some networks, a VPN might be connected to multiple MCEs. When one MCE advertise the routes learned from BGP to the VPN, the other MCEs might learn the routes, resulting in routing loops. To avoid such routing loops, you can configure route tags for VPN instances on an MCE. H3C recommends configuring the same route tag for the same VPN on the MCEs. import-route protocol [ process-id 6. Redistribute remote site routes | allow-ibgp ] [ cost cost | type advertised by the PE. type | tag tag | route-policy route-policy-name ] * By default, OSPF does not redistribute routes from any other routing protocol. 7. (Optional.) Configure OSPF to redistribute the default route. default-route-advertise summary cost cost By default, OSPF does not redistribute the default route. This command redistributes the default route in a Type-3 LSA. The MCE advertises the default route to the site. 8. Create an OSPF area and enter OSPF area view. area area-id By default, no OSPF area is created. 9. Enable OSPF on the interface attached to the specified network in the area. network ip-address wildcard-mask By default, an interface does not run OSPF. Configuring IS-IS between an MCE and a VPN site An IS-IS process belongs to the public network or a single VPN instance. If you create an IS-IS process without binding it to a VPN instance, the process belongs to the public network. Binding IS-IS processes to VPN instances can isolate routes of different VPNs. To configure IS-IS between an MCE and a VPN site: Step 1. Enter system view. 2. Create an IS-IS process for a VPN instance and enter IS-IS view. 3. Configure a network entity title. Command system-view isis [ process-id ] vpn-instance vpn-instance-name network-entity net 9 Remarks N/A Perform this configuration on the MCE. On the VPN site, configure a normal IS-IS process. By default, no NET is configured.
