6. 对于9.9.9.9/32网络，为了在AS 65001内部优选R4作为路径，需将Local Preference设置为200。
# R4：
access-list 1 permit 9.9.9.9
route-map R9 permit 10
match ip address 1
set local-preference 200
route-map R9 permit 20
router bgp 65001
neighbor 1.1.1.1 route-map R9 out
neighbor 2.2.2.2 route-map R9 out
7. 100.1.3.0/24、100.1.4.0/24、100.2.3.0/24、100.2.4.0/24网络必须在R3上通过Community属性传播至R9。此时，Community值需设置为65001:100。
# R3：
access-list 10 permit 100.1.3.0 0.0.0.255
access-list 10 permit 100.1.4.0 0.0.0.255
access-list 10 permit 100.2.3.0 0.0.0.255
access-list 10 permit 100.2.4.0 0.0.0.255
route-map COM permit 10
match ip address 10
set community 4259905636
# set community 65001:100
route-map COM permit 20
router bgp 65001
neighbor 5.5.5.5 send-community both
neighbor 5.5.5.5 route-map COM out
# R5：
router bgp 65005
neighbor 9.9.9.9 send-community both
