我正在尝试为此配置设置本地首选项

通过 R3 建立从 R1 到 R4 的路由。这就是我配置 R3 的方式

R3#conf term
Enter configuration commands, one per line.  End with CNTL/Z.
R3(config)#route-ma
R3(config)#route-map
% Incomplete command.

R3(config)#route-map bakatele permit 12
R3(config-route-map)#set local-preference 213
R3(config-route-map)#exit
R3(config)#exit
R3#
*Mar  1 05:28:42.506: %SYS-5-CONFIG_I: Configured from console by console
R3#conf ter
Enter configuration commands, one per line.  End with CNTL/Z.
R3(config)#router bgp 230
R3(config-router)#neighbor 10.0.34.2 route-map bakatele in
R3(config-router)#exit
R3(config)#exit
R3#conf term

之后，我获得了本地首选项设置：

R3#show ip bgp
BGP table version is 3, local router ID is 3.3.3.3
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
              r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

   Network          Next Hop            Metric LocPrf Weight Path

*  192.168.41.0     10.0.35.2                              0 500 400 i

* i                 10.0.24.2                0    100      0 400 i
*  192.168.51.0     10.0.35.2                0             0 500 i
*>                  10.0.34.2                     213      0 400 500 i
* i                 10.0.24.2                0    100      0 400 500 i

但是在检查 trace-route 命令之后似乎没有任何改变，因为在设置首选项之前和之后，trace-route 看起来完全一样：

R1#traceroute 192.168.41.1 source 192.168.11.1

Type escape sequence to abort.
