簡介

本文檔介紹並提供虛擬路由和轉發(VRF)路由洩漏的常用方法的配置示例。

思科建議您瞭解以下主題：

採用元件

本檔案中的資訊是根據使用Cisco IOS® XE版本16.12.X和17.X的路由器

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。

背景資訊

VRF允許路由器為不同的虛擬網路維護單獨的路由表。當需要異常時，VRF路由洩漏允許在VRF之間路由某些流量，而不使用靜態路由。

場景1 - BGP和IGP之間的VRF路由洩漏(EIGRP)

案例1提供了BGP和EIGRP之間的VRF路由洩漏示例。此方法可用於其他IGP。

網路圖表

如圖1所示的網路圖顯示了需要路由洩漏的第3層拓撲。

Route Leaking Topology for Scenario 1
圖1.案例1的路由洩漏拓撲

路由器「LEAK」具有到VRF A中鄰居的BGP鄰居關係，以及全域性VRF中的EIGRP鄰居關係。裝置192.168.11.11需要能夠通過網路連線到裝置172.16.10.10。

由於路由位於不同的VRF中，路由器LEAK無法在兩者之間路由。這些路由表顯示每個VRF的當前路由，並指明哪些路由需要在全域性VRF和VRF A之間洩漏。

設定

請按照以下步驟在兩個路由表之間建立洩漏：

Step 1.
Create route-maps to filter the routes to be injected in both routing tables.

LEAK(config)#Route-map VRF_TO_EIGRP
LEAK(config-route-map)#match ip address prefix-list VRF_TO_EIGRP
LEAK(config-route-map)#exit
!
Prefix-list created to match the host that is attached to the previous route-map configured.
!
ip prefix-list VRF_TO_EIGRP permit 172.16.10.10/32

or

LEAK(config)#Route-map VRF_TO_EIGRP
LEAK(config-route-map)# match ip address 10 
LEAK(config-route-map)#exit
!
ACL created to match the host that is attached to the previous route-map.
!
LEAK#show ip access-lists 10 
10 permit 172.16.10.10

LEAK(config)#Route-map EIGRP_TO_VRF
LEAK(config-route-map)#match ip address prefix-list EIGRP_TO_VRF 
LEAK(config-route-map)#exit
LEAK(config)#
!
Prefix-list created to match the host that is attached to the previous route-map configured.
!
ip  prefix-list EIGRP_TO_VRF  permit 192.168.11.11/32

or

LEAK(config)#Route-map EIGRP_TO_VRF
LEAK(config-route-map)#match ip address 20 
LEAK(config-route-map)#exit
LEAK(config)#
!
ACL created to match the host that is attached to the previous route-map.
!
LEAK#show ip access-list 20
10 permit 192.168.11.11


Step 2.
Define the import/export maps and add the route-map names.

LEAK(config)#vrf definition A 
LEAK(config-vrf)#address-family ipv4 
LEAK(config-vrf-af)#import ipv4 unicast map EIGRP_TO_VRF >> Import the global routing table routes at the VRF routing table.
LEAK(config-vrf-af)#export ipv4 unicast map VRF_TO_EIGRP >> Export the VRF routes to the Global Routing Table.
LEAK(config-vrf-af)#end

Step 3. 
Proceed with the dual redistribution.

Redistribute EIGRP 

LEAK(config)#router bgp 1
LEAK(config-router)#redistribute eigrp 1 
LEAK(config-router)#end

Redistribution BGP

LEAK(config)#router eigrp 1
LEAK(config-router)#redistribute bgp 1 metric 100 1 255 1 1500 
LEAK(config-router)#end

設定

執行以下步驟在兩個路由表之間建立洩漏：

Step 1.
Create route-maps to filter the routes to be injected in both routing tables.

LEAK(config)#Route-map VRFA_TO_VRFB 
LEAK(config-route-map)#match ip address prefix-list VRFA_TO_VRFB 
LEAK(config-route-map)#exit

!
LEAK#show ip access-lists 20 
10 permit 192.168.11.11
20 permit 192.168.1.0

Step 2.
At the VRFs configure the import/export map, use the route-map names to leak the routes.

LEAK(config)#vrf definition A 
LEAK(config-vrf)#address-family ipv4 
LEAK(config-vrf-af)#export map VRFA_TO_VRFB 
LEAK(config-vrf-af)#import map VRFB_TO_VRFA

LEAK(config-vrf)#address-family ipv4 
LEAK(config-vrf-af)#export map VRFB_TO_VRFA 
LEAK(config-vrf-af)#import map VRFA_TO_VRFB 

Step 3.
Add the route-target to import and export the route distinguiser from both VRFs.

route-target export 1:2

執行以下步驟在兩個路由表之間建立洩漏：

Step 1.
Create route-maps for import and export to be injected in both routing tables.

LEAK(config)#Route-map OSPF_TO_EIGRP
LEAK(config-route-map)#match ip address prefix-list OSPF_TO_EIGRP 
LEAK(config-route-map)#exit

!
LEAK#show ip access-lists 20
10 permit 192.168.11.11
20 permit 192.168.1.0/24

Step 2.
Add the import/export maps in order to match the route-map names.

Current configuration
!
vrf definition B
rd 1:2 
!
address-family ipv4 
exit-address-family
!
!
LEAK(config-vrf)#vrf definition B 
LEAK(config-vrf)#address-family ipv4 
LEAK(config-vrf-af)#import ipv4 unicast map EIGRP_TO_OSPF
LEAK(config-vrf-af)#export ipv4 unicast map OSPF_TO_EIGRP

Step 3.
To perform the leak is necessary to create a BGP process, in order to redistribute 
the IGPs protocols.

router bgp 1
bgp log-neighbor-changes
! 
address-family ipv4 vrf B >> Include the address-family to inject VRF B routing table (OSPF)
!
exit-address-family

註：確保VRF配置了路由區分器以避免錯誤：
"%vrf B does not have "rd" configured, please configure "rd" before configuring import route-map"

Step 4.
Create a Dual Redistribution.

IGPs redistribution.

LEAK(config-router)#router bgp 1 
LEAK(config-router)#redistribute eigrp 1
!
LEAK(config-router)#address-family ipv4 vrf B 
LEAK(config-router-af)#redistribute ospf 1 match internal external 1 external 2 
LEAK(config-router-af)#end

BGP Redistribution

LEAK(config)#router ospf 1 vrf B 
LEAK(config-router)#redistribute bgp 1
