核心交换机配置

三层结构，vlan网关放在汇聚交换机，各个汇聚交换机绑定地址192.12.101.xxx，与核心机利用此地址段以路由模式互通，汇聚机没有配置路由；外网防火墙的接口地址为192.12.101.252，核心机出口地址为192.12.101.254，核心机有默认路由：ip route-static 0.0.0.0 0 192.12.101.252。汇聚层和接入层的电脑与该核心机的三层互联网关地址192.12.101.254不通，所以无法上外网，怎么解决？

核心机配置如下：dis cu # version 7.1.070, Release 7585P05 # sysname HeXin # clock protocol none # telnet server enable # forward-path-detection enable # irf mode normal # ospf 1 router-id 192.12.100.1 area 0.0.0.0 #
