我怎样才能结合这些线

Question

我如何组合这些行（注意：这只是一个更大文件的摘录）：

interface GigabitEthernet0/0
 no ip proxy-arp
interface GigabitEthernet0/0.202
 no ip proxy-arp
interface GigabitEthernet0/0.358
 no ip proxy-arp
interface FastEthernet0/0/1.26
 no ip proxy-arp
interface GigabitEthernet0/0
 no ip proxy-arp
interface GigabitEthernet0/0.202
 no ip proxy-arp
interface GigabitEthernet0/0.358
 no ip proxy-arp
interface FastEthernet0/0/1.26
 no ip proxy-arp
interface Loopback0
 no ip proxy-arp
interface Loopback1
 no ip proxy-arp
interface Loopback26
 no ip proxy-arp
interface GigabitEthernet0/0/0
 no ip proxy-arp

使它们类似于：

interface GigabitEthernet0/0 | no ip proxy-arp
interface GigabitEthernet0/0.202 | no ip proxy-arp
interface GigabitEthernet0/0.358 | no ip proxy-arp
interface FastEthernet0/0/1.26 | no ip proxy-arp
interface GigabitEthernet0/0 | no ip proxy-arp
interface GigabitEthernet0/0.202 | no ip proxy-arp
interface GigabitEthernet0/0.358 | no ip proxy-arp
interface FastEthernet0/0/1.26 | no ip proxy-arp
interface Loopback0 | no ip proxy-arp
interface Loopback1 | no ip proxy-arp
interface Loopback26 | no ip proxy-arp
interface GigabitEthernet0/0/0 | no ip proxy-arp

我尝试了一些在网上找到的不同解决方案，但似乎没有一个适合我的情况
