# Example: Stripping the Domain Name per Virtual Router for RADIUS Server Authentication

This example demonstrates the strip domain functionality for a virtual router.

1. Configure the virtual router.
   host(config)#profile VR1 host(config-profile)#ppp authentication virtual-router vr1 pap chap host(config-profile)#exit host(config)#profile VR2 host(config-profile)#ppp authentication virtual-router vr2 pap chap host(config-profile)#exit host(config)#profile VR3 host(config-profile)#ppp authentication virtual-router vr3 pap chap host(config-profile)#exit host(config)#profile VR4 host(config-profile)#ppp authentication virtual-router vr4 pap chap host(config-profile)#exit host(config)#profile VR5 host(config-profile)#ppp authentication virtual-router vr2 pap chap host(config-profile)#exit
2. Access the context of a previously created virtual router and enable the strip domain functionality for each virtual router.
   host(config)#virtual-router vr1 host:vr1(config)#aaa strip-domain enable host:vr1(config)#aaa strip-domain delimiter domainName $ host:vr1(config)#aaa strip-domain parse-direction domainName left-to-right host:vr1(config)#radius authentication server 10.209.154.193 host:vr1(config)#key bras host:vr1(config)#exit host:vr1(config)#radius accounting server 10.209.154.193 host:vr1(config-radius)#key bras host:vr1(config-radius)#exit host:vr1(config)#virtual-router vr2 host:vr2(config)#aaa strip-domain enable host:vr2(config)#aaa strip-domain parse-direction domainName left-to-right host:vr2(config)#radius authentication server 10.209.154.194 host:vr2(config-radius)#key bras host:vr2(config-radius)#exit host:vr2(config)#radius accounting server 10.209.154.194 host:vr2(config-radius)#key bras host:vr2(config-radius)#exit host:vr2(config)#virtual-router vr3 host:vr3(config)#radius authentication server 10.209.154.193 host:vr3(config-radius)#key bras host:vr3(config-radius)#exit host:vr3(config)#radius accounting server 10.209.154.193 host:vr3(config-radius)#key bras host:vr3(config-radius)#exit host:vr3(config)#virtual-router vr4 host:vr4(config)#aaa strip-domain enable host:vr4(config)#aaa strip-domain delimiter domainName % host:vr4(config)#radius authentication server 10.209.154.194 host:vr4(config-radius)#key bras host:vr4(config-radius)#exit host:vr4(config)#radius accounting server 10.209.154.195 host:vr4(config-radius)#key bras host:vr4(config-radius)#exit host:vr4(config)#virtual-router vr5 host:vr5(config)#aaa strip-domain enable host:vr5(config)#radius authentication server 10.209.154.193 host:vr5(config-radius)#key bras host:vr5(config-radius)#exit host:vr5(config)#radius accounting server 10.209.154.192 host:vr5(config-radius)#key bras host:vr5(config-radius)#exit

Based on the virtual router’s configuration, Table 4 lists the final user name for each virtual router applied.
