[c-nsp] ISDN backup for MPLS CE Router

[Zitouni Rachid]

Hi,

Use dialer watch:  http://www.cisco.com/en/US/tech/tk801/tk379/technologies_configuration_example09186a0080094143.shtml  

On CE : you will need your default route to PE  to be suppressed when CE-PE link fail somewhere => dynamic routing is the easier way to do it

Obviously, your Head Office CE will need to know that the link between branch office CE and PE went down....

The CE will have ISDN WIC and it should dial out to my Head Office  ISDN Aggregator (Cisco 3845) when the default route from ISP is missing.

 

After this if at all there is a problem in MPLS cloud ( either ETH going down / route missing )from service provider data will flow Via ISDN .

Just to make sure I understand your topology :

ISDN will be CE-PE or CE-CE ?

Hi Friends,

 

Most of my branches connect to MPLS service provider using a ETH port on

my CE.

 

I am thinking of having a ISDN Backup for the MPLS VPN Link.

 

Since ETH its very rare that the interface go down, So I have to look

for the default route that ISP gives to my CE and if not available I

will have to start ISDN. 

 

Please help me with some of your experience or documentation.
