Cost Community for EIGRP over MPLS VPN

Hi Experts,

I have some doubt in Cost Community. Please find below output for understand
my Problem:

*Problem 1:* Tag value will be always zero regardless of internal or
external route? Can we change it ? If Yes, how?

0x8800: Flag : Tag

*0x8800:32768:0* ( Internal Route)

*0x8800:0:0* ( External Route)

*Problem 2*: Actual Delay = Delay Metric *10/256 = 153600 * 10/256= 6000
usec

10/256 is fixed or variable?

0x8800 : AS : DELAY

*0x8801:101:153600

**Problem 3*: Actual BW = 10M/ BW Metric * 256 = 10M/25600 * 256 = 10,000
Kbit
*
 * 10M/ BW Metric is fixed or variable.

0x8802: RELIABILITY + NEXT HOP : BW
*
0x8802:65281:256000*

*Problem 4 : *

0x8800 : REMOTE AS : REMOTE ID

Remote AS is zero. ( Becoz it is a non EIGRP Route)

It will be always zero for External Route?

Problem 5 :

0x8800 : Remote Protocol : REMOTE METRIC

Remote Protocol Values are:

1 IGRP
2 EIGRP
3 Static
4 RIP
*5 HELLO*
6 OSPF
7 IS-IS
8 EGP
9 BGP
*10 IDRP*

How to Use Value 5 and 10 ?

In My output i am getting value 11. That is not mention anywhere? I got this
value by redistribute connected command under EIGRP on CE router.

*0x8805:11:0*

Remote Metric will always be zero? If yes, How we can Change it?

Thanks in advance.

Regards,

Gaurav
